Cube (algebra)

In mathematics, a cube of a number means the result of multiplying the number by its square. For example, the cube of 6 is 6×6×6 = 216.
It is named this because cubing a number gives the volume of a cube.
Cubing a number can also be written as 63 = 36. Cubing is the same as raising to the power of 3.
Many of the units of volume are cubes. For example, a "cubic meter" means the volume equal to the volume of a cuboid which is one meter tall, one meter wide, and one meter deep.
