**Cube:-**

The cube of a number n is its third power: the result of the number multiplied by itself twice: a3 = a x a x a.

**Cube numbers:-**

Numbers that are obtained when a number is multiplied by itself two times are

known as cube numbers. If a natural number m can be expressed as n3, where n is also a natural number then m is a cube number.

**Cube root:-**

Cube root is the inverse operation of cube. If ‘a’ is a natural number such that n3 = a, then √?3 denotes the cube root of n.
