Is the area of the desk about 32 centimeters right or wrong?

Of course, it's wrong, how can there be centimeters in the area, it can only be square centimeters or square decimeters, and the table is not as small as 32 square centimeters.

This is wrong. The first is the question of the category of units. The centimeter is the unit of length, and the unit of area is the square centimeter, the square decimeter, and the square meter of these units.

The desk is rectangular, multiplied by length, the unit of length and width is centimeter, in addition to the number to multiply the area, the unit should also be multiplied, the centimeter multiplied by the centimeter is the square centimeter, and the same can be obtained.

The second is the issue of the size of the unit. 32 square centimeters is too small, it's about a desk with a length of centimeters and a width of 5 centimeters, which is also too small. The unit should be square decimeter (1 square decimeter = 100 square centimeters), and the length of the decimeter (1 decimeter = 10 centimeters) and the width of 5 decimeters is in line with reality.

Wrong! Centimeter is a unit of length. The area cannot be expressed in terms of length (32 cm).

The area of the desk is about 32 cm, which is wrong. Because the area is not calculated in centimeters, it should be the square of centimeters, and the area of the desk should be about 32 square centimeters.

If the area is 32 cm and the cross-section of the desk is rectangular (rectangular), then the length and width should be 8 cm and 4 cm, which is obviously illogical and therefore wrong.

This statement must be wrong. Because we represent the surface base as squared. Even if the answer is correct, it should be 32 square centimeters.

Such a statement must be very wrong, because the area must be square centimeters and not centimeters, so the area of the desk should be 32 square centimeters, such a statement is correct.

The unit of area can be square centimeters, and the area of a desk is about 32 square centimeters, which is too small. A piece of A4 paper is also 625 square centimeters! The area of 32 square centimeters is not as large as the area of a mobile phone.

Wrong, first of all, the unit of area is square, and secondly, it is not 32 square centimeters, it should be about 2 square meters.

Let's start with centimeters.

It's a unit of length, and it's wrong.

The area is squared, and if you say 32c, it is also not right, it is too small.

The square decimeter is reasonable.

This is a matter of common sense, if it is 70 square centimeters, 70 square meters are obviously wrong, so 70 square decimeters is correct.

This must be wrong, first of all, the unit of area cannot be centimeters, centimeters is a length, and the unit area is calculated by squares.

The area of a desk table is about 40 square decimeters.

Perhaps the desk that remains in our memory the most is probably the oneLu XunThe desk engraved with the word "morning" was thus interpreted into the desk culture of the year (desk culture such as graffiti and lettering on the desk). The functional size standards of desks and stools are mainly based on anthropometric data and special surveys in China in recent yearsMinistry of HealthIt was proposed that the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China revised and promulgated it in 2002, and the previous two old standards were abolished at the same time.

Desks are divided into "No. 4" and "No. 5" two labels, respectively for junior high school and primary school students, and it is recommended that "No. 4" desks and chairs are mainly used by first-year junior high school students, and the table height of "No. 4" desks is 67 cm. For some students with special heights, the school can arrange desks and stools separately.

The desks that are realized today are mainly divided into the following three categories:

Solid Wood Desks: In 2000, most schools used this traditional single and double desks made of solid wood. This kind of desk is easy to process, the material is miscellaneous wood, a lot of wood is wasted, and it is not durable, and it is still used by primary and secondary schools in many poor areas.

Due to the fixed height of the desks and stools, they are gradually replaced by adjustable desks with steel-plastic structures.

Adjustable desk: also known as adjustable desk, as the name suggests, is the height of the desk and stool can be adjusted, and the height of the desk can be adjusted up and down between the sliding shafts through the relevant firmware of the table legs, so as to meet the needs of the school and students. This type of desk is mainly made of steel and plastic structure, and the desktop is melamine board.

The table legs are steel pipe fittings, and the relevant connecting ground parts are protected by plastic caps.

Rubber and plastic desks: mainly made of rubber and plastic alloy materials.

School desks and chairs are mechanically molded, which are mostly fixed structures and cannot be adjusted in height, but because of the special materials used, the material is good, durable and lightweight, and has also been adopted by some schools.

A: The area of a desk is about 40 square decimeters.

The area of the desk is about 24 square decimeters.

In fact, there is no fixed size of the desk, and the size used by students of different ages will be different, usually the area of the desk is about 40 square decimeters. Desks generally include solid wood desks, lifting desks and rubber and plastic desks.

Expand your knowledge:

Desks for students, starting from the octagonal tables in the earliest schools, are used in schools, and the desks used for school learning should be bent and unified into desks. Perhaps the most profound desk left in our memory may be Lu Xun's desk engraved with the word "morning", which deduced into the desk culture of the year (specially graffiti on the desk, lettering and other desk burial culture).

The functional size standards of desks and stools, mainly based on anthropometric data and special surveys in China in recent years, were proposed by the Ministry of Health Hayano and revised and promulgated by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China in 2002, and the previous two old standards were abolished at the same time.

Desks are divided into "No. 4" and "No. 5" two labels, respectively for junior high school and primary school students, and it is recommended that "No. 4" desks and chairs are mainly used by first-year junior high school students, and the table height of "No. 4" desks is 67 cm. For some students with special heights, the school can arrange desks and stools separately.

When the space occupied by an object is a two-dimensional space, the size of the space occupied is called the area of the object, which can be flat or curved. The square meter, square decimeter, square centimeter, is a recognized unit of area.

Desks are generally rectangular, i.e., rectangular.

Rectangle area = length and width.

Since 42 = 6 7

So, the side length of this table is about 6 and 7.

Obviously, it won't be 6 meters or 7 meters, it's too big, it's the size of a classroom.

It won't be 6 cm or 7 cm, it's too vertical to hold small, and it's about the same as a business card.

That's 6 decimeters and 7 decimeters, and it's about the same length as a desk.

6 decimeters 7 decimeters = 42 square decimeters.

A: It is about 42 square meters of Qing square decimeter.

The area of a desk table is about 40 square decimeters.

The length of the desk is about 1 meter, the width is about 40 centimeters, the area is about 40 square decimeters, the length units are kilometers, meters, decimeters, centimeters, millimeters, the advance rate between kilometers and meters is 1000, and the advance rate between the other two adjacent units is kilometers = 1000 meters, 1 meter = 10 decimeters, 1 decimeter = 10 centimeters, 1 centimeter = 10 millimeters, 1 millimeter = 1000 microns, 1 micron = 1000 nanometers, 1 nanometer = 10 a.

For example, centimeters are the units of length, grams are the units of mass, and seconds are the units of time. As an example of mathematics, it can also be said that 1 is the unit of a natural number and the fraction of 1 is the unit of fractions. When measuring the length of a line segment, it is necessary to select a certain line segment as the measurement standard, and stipulate that its length is 1, and call this line segment a unit of length.

The answer is as follows: the area of the desk is about 40 square decimeters. There is no fixed size of the desk, and the size used by students of different ages will have a certain difference, usually the area of the desk is about 40 square meters of Qingshu decimeter.

Desks generally include solid wood desks, lifting desks and rubber and plastic desks. At present, in many primary and secondary schools in poor mountainous areas, solid wood desks are used, although this kind of desks are easy to process, but they waste a lot of wood and are not durable. The height-adjustable desk is mainly a steel-plastic structure, and the desktop is made of melamine board, and the table legs are steel pipe fittings, and the relevant places connected to the ground are protected by plastic caps.

The area of the desk is about 44 (square decimeters);

The table is rectangular, with an area of 44 square decimeters, a length of about 11 decimeters, and a width of 4 decimeters. This is more realistic. If you fill in other area units, it should not be too large, or not too small, 11 decimeters and 4 decimeters are more suitable, so that the length is 110 centimeters and the width is 40 centimeters.

The area of the desk is about 44 (square decimeters);

44 square decimeters corresponds to the area of a rectangle 10 decimeters long and 10 decimeters wide, which is in line with the situation of desks in normal life.

The unit of expression of area in our daily life also has square centimeters, square meters, etc., but square centimeters cannot be used to measure the desk, 44 square meters is equivalent to the area of an apartment, which is obviously unreasonable, so the area of the desk is about 44 square decimeters is the most reasonable.

If the length and width are measured in cm, the area is cm

If it is measured in dm, the area is dm
