Cube Root Method 

What is a Cube Root of a number? 

The cube root of a number is defined as the number which results in the original number when it is cubed. For example, for 8, the cube root will be 2 as 2×2×2 = 8. 

What is a Perfect Cube number?

A perfect cube is a number that can be expressed as the cube of an integer or as the third exponent of an integer. For example, 64 is a perfect cube because it is the cube of integer 4,      4 × 4 x 4 = 64. However, 21 is not a perfect cube number because it cannot be expressed as the cube of any integer.
