To find the cube of a number, we will multiply the number three times of which we have to find the cube.

• First, we will apply the exponent 3 on the base 6 which will be equal to the multiplication of the given number thrice and then we will multiply the first two numbers, here both the numbers are 6.
• Then we will again multiply the same number with the calculated product of the first two numbers.
• After this, we will get the required cube of the given number.

Therefore 31 cube is =>

31 × 31 × 31

=> 961 × 31
