**How to Cube a Negative Number**

The method of cubing a negative number is the same as squaring a number. A number is cubed when it is multiplied three times by itself. A positive number’s cube will always be positive, while a negative number’s cube will always be negative.

**For example,**

Cube of negative number : (-3^{3}) = -3 x -3 x -3 = -27

Cube of positive number : (3^{3}) = 3 x 3 x 3 = 27
