1. In algebra, a cube is a power operation with an exponent of 3, also called a cube. The cube of a number is equal to the number multiplied by itself three times in a row, such as the cube of a =a×a×a, and it is recorded as a_. The number of a cube equal to itself is only 1, 0,-1. The cube of positive numbers is positive numbers, the cube of 0 is 0, and the cube of negative numbers is negative numbers.
2. In graphics, a cube is a quantifier to measure the volume of an object. Volume of cuboid = length× width× volume of high cube = side length× side length× volume of cylinder with side length = bottom area× volume of high cone = 1/3× bottom area× height. For example, when the pool is 2, its width is 1.3 and its height is 1.4. The volume of water that the pool can hold =2x 1.3x 1.4=3.64.

Cubic calculation formula and method
Cubic calculation formula and method:
1, cubic V=a_
2. cuboid V= length x width x height
3. Sphere V=4πr_/3
4. For other three-dimensional graphics, we can try to deduce the cubic calculation formula by triple integral.

If the cube of a number is equal to A, then this number is called the cube root of A, also called the cube root. That is, if x_=a, then X is called the cube root of A. Note: the root index 2 in the square root can be omitted, but the root index 3 in the cube root cannot be omitted.
