What is called volume How to calculate and how is volume calculated

volume: pronunciation tǐjī, English name [volume; size;capacity] refers to the size of the space occupied by a substance or object, the amount of matter that occupies a specific volume. The volume of an object is a physical quantity, and the symbol is v.

The basic unit of volume of an object in the International System of Units is the cubic meter, which is represented by the symbol m. The commonly used units are cubic centimeters, cubic decimeters, and the volume units of liquids are milliliters (ml) and liters (l), one milliliter is equal to one cubic centimeter, and one liter is equal to one cubic decimeter. The volume of the same substance is proportional to its mass, and the ratio of its mass to volume is the density of the substance.

For example, if the volume of a wooden box is 3 cubic meters, two volumes of hydrogen and one volume of oxygen are released when water is electrolyzed.

Commonly used volume units: cubic meters, cubic decimeters, cubic centimeters Common calculations of volume (v = volume, a = length, b = width, c or h = height, s = area) volume of the cuboid = length width height v = abc

The volume of the cube = edge length 3 v=a 3

Volume of the cylinder = base area height v=sh

The volume of the cone = the base area height 3 v=sh 3

The volume of the ball is calculated by the formula v ball = 4 3 r3 ( is a constant i.e. pi is approximately equal to, r = radius of the ball).

The first in the world to come up with the correct formula for calculating the volume of a sphere was the mathematician Zu Chongzhi of the Southern Dynasty, about a thousand years earlier than the Europeans. He also studied the art of celestial arithmetic (astronomical mathematics) and refined the Great Meiji period, which was officially promulgated in 510 at his repeated requests. He also made a variety of precision observation instruments such as the bronze day (an instrument that uses the method of measuring the shadow of the sun to keep time) and a leaky pot, which were adopted by later generations.

The picture on the right shows the world's first person to calculate the volume of a ball ---ancient Chinese mathematician Zu Chongzhi).

To volume is the amount of space occupied by the object, that is, the capacity. The calculation depends on what volume you are calculating.

Volume: The amount of space occupied by an object.

The volume is calculated by multiplying the width by the height of the Lagao brother.

Usually we use the length multiplied by the width multiplied by the height.

Of course, the formula for calculating the volume of objects of different shapes is different, and the following are the formulas for calculating the volume of various figures:

1. The volume of the cube is equal to a, and a is the edge length.

2. The volume of the box is equal to the length multiplied by the width multiplied by the height.

3. The volume of the cylinder is equal to the base area multiplied by the height and the radius multiplied by the radius multiplied by the height.

4. The volume of the cone is equal to the base area multiplied by the height divided by 3 equals the radius multiplied by the radius multiplied by the height divided by 3.

The usefulness of volumes:

Volume refers to the amount of space occupied by an object. It is usually expressed as cubic units (like cubic meters, cubic centimeters, etc.). Volume is related to the size and shape of an object and can be calculated by measuring its length, width, and high parameters.

In the fields of scientific research, engineering design, manufacturing, etc., it is very important to accurately measure and calculate the volume of objects. Through the knowledge of the volume of an object, one can better understand its properties and characteristics, and rotate for rational use, processing, and transportation.

We also often use the concept of volume in our daily lives, for example, when buying items, we need to consider the amount of space they occupy, or when making home placement plans, we need to determine the volume of furniture. <>

Physical Formula <>

Volume is calculated: volume = length, width, height.

Volume, a geometric term. When the space occupied by an object is three-dimensional space, the size of the space occupied is called the volume of the object.

The SI system of units for volume is cubic meters. One-dimensional objects (e.g., lines) and two-dimensional objects (e.g., squares) are zero-volume.

is a numerical value used to describe the space occupied by the object in three-dimensional space. One-dimensional objects (e.g., lines) and two-dimensional objects (e.g., squares) are zero-volume in three-dimensional space.

Stereo geometry can be divided into the following categories:

1. Cylinder: including cylinder and prism. Prism can be divided into straight prism and oblique prism, and can be divided into triangular prism, quadrangular prism and n prism according to the number of bottom edges; The volume of the prism is equal to the base area multiplied by the height, i.e., v=sh.

2. Pyramid: including cone and pyramid, the pyramid is divided into three pyramids, four pyramids and N pyramids.

3. Rotating body: including cylinder, round table, cone, ball, ball crown, bow ring, ring, embankment ring Mintan, fan ring, jujube kernel, etc.

4. Cross-sectional body: including prism, round table, oblique truncated cylinder, oblique truncated prism, oblique truncated cone, ball crown, ball gap, etc. Its surface area and volume are generally solved according to the addition and subtraction of the graph. <>
