Cube (algebra)

In arithmetic and algebra, the cube of a number n is its third power: the result of the number multiplied by itself twice:

It is also the number multiplied by its square:

This is also the volume formula for a geometric cube with sides of length n, giving rise to the name. The inverse operation of finding a number whose cube is n is called extracting the cube root of n. It determines the side of the cube of a given volume. It is also n raised to the one-third power.
