# Cube Formula

Cube of any digit, forms by multiplying the digit by itself three times. For instance, to find the $5^{3}$ we need to multiply 5 three times: 5 $\times$ 5 $\times$ 5 = 125

Note: we write down “5 cube” as $5^{3}$  (the little 3 means the number appears three times during the multiplication process.

The Cube Formula for any value ‘x’ is given as,

$\LARGE x^{3} = x \times x \times x$

### Solved Examples

Question 1: What is the cube of 15?
Solution:
The formula for calculating cube is,
$x^{3} = x \times x \times x$
Here, x = 15
$15^{3}$ = 15 $\times$ 15 $\times$ 15
$15^{3}$ = 3375
Question 2: What is the value of x if $x^{3}=27$
Solution:

The formula for calculating cube is,
$x^{3} = x \times x \times x$
Here, $x^{3}=27$
$x=\sqrt[3]{27}$
$x = 3$
