The area of the cover of a math book is approximately square centimeters

The area on the cover of a mathematics textbook is generally found in the fourth grade of primary school.

Generally, it refers to the area of one side of the front of the textbook.

The cover of a math book is rectangular, generally 30 cm long and about 20 cm wide.

The unilateral area of math textbooks is based on the formula of rectangular area: area = length x width.

It is generally 30 cm x 20 cm, about 600 square centimeters.

Here's about how much.

The square centimeter requires visual inspection and estimation, and there is no very accurate value.

Some math textbooks are about 20 centimeters long and 15 centimeters wide. The area is about 300 square centimeters.

The cover of a math book is equivalent to a rectangle, and the area of the rectangle is.

Length times width. Calculate the cover of the math book. Long. And.

Wide. After multiplication, you can do it.

For example, if the cover of a math book is 18cm on one side and 25cm on the other, then it is. cm²

40 square centimeters. The process of solving the problem is as follows:

1. The cover area of a mathematics book is about 40 square centimeters, which is consistent with the actual situation, 4 square decimeters 400 square centimeters, 400 square centimeters is 15 centimeters long and about 26 6 centimeters wide, which is the size of a book.

Square centimeters, this area is too small, a book cannot be as big as 4 square centimeters, 4 square centimeters means 2cm long and 2cm wide. The length and width of the book are more than 2 cm.

square centimeters, this area is too large.

Extended Information: Other Area Calculations:

Rectangle (rectangle): {rectangle area length width}

Square: {square area side length side length}

240 square centimeters cm 15...5

Centimeter. A book without such a small cover.

So the area of the cover of the math book is about 240 square centimeters, which is not right.

The area of the cover of the math textbook is about 5 square decimeters.

Textbooks are essential tools for students in learning, and they are common things in life, and the area of the cover of mathematics textbooks is about 5 square decimeters, which is equivalent to the area of a square with a side length of 50 centimeters (5 decimeters) and a width of 10 centimeters (1 decimeter).

Before 2001, China used unified textbooks, which were compiled by the Ministry of Education and the People's Education Publishing House, and published by the People's Education Publishing House for use throughout the country. After 2001, the Compulsory Education Curriculum Standards and the General Senior High School Curriculum Standards were issued, and textbooks could be published by various publishing houses and then approved and used by the Ministry of Education.

It can be divided into three categories: primary school textbooks, middle school textbooks and college textbooks.

Hello, it is a pleasure to serve you. I am a special guest teacher Xiaoxiao, with 5 years of teaching experience, 2000+ consulting experience, good at primary and secondary education research, proficient in various science knowledge and literary knowledge.

Hello, the math book cover is about 500 square centimeters.

Generally speaking, the cover of a math book is 50 cm long and 10 cm wide, so you can list the equation to find the area of 50*10 500, so the area of the cover of a math book is about 500 square centimeters.

This question mainly examines the calculation of multiplication, and our perception of the size of the objects we see in daily life can be paid more attention to and practiced more.

If you don't understand, you can ask me.

Feel free to pay a little attention, and don't get lost in the next consultation Welcome to consult again

Life is not easy, the evaluation of the pro is very important to me If the answer is helpful to you, you can end the consultation, please click on the evaluation of five little stars Thank you very much! Your encouragement is my biggest motivation

The cover area of a math book is about 40 square centimeters, which is consistent with the actual situation, 4 square decimeters = 400 square centimeters, 400 square centimeters is 15 centimeters long and about centimeters wide, which is the size of a book.

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 the recognized unit of area, which can be expressed by letters as (m, dm, cm).

The cover of a math book is generally long and wide, which is the length and width of a math book in my area, and the area is long times wide. The area is as follows s=, so the area of the cover of a math book is about 240 square centimeters.

The length of the math book is about 30 centimeters and the width is about 20 centimeters.

So their area = 30 20 = 600 square centimeters.

Roughly estimate the length and width of the length to find their area.

The area of the cover of the math book:

25 15 = 375 380 square centimeters.

If it's a low grade math book, the area of the math book may be quite small, and if it is a high school student or a college student, the area of the math book may be quite large, and it may be several times different.

Hello, glad for your question!

The math books are not the same size in each place, so you can use a ruler to measure the length and width of your math books, and then multiply them.
