# 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

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

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, $x^{3}=27$

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

Here, $x^{3}=27$

$x=\sqrt[3]{27}$

$x = 3$
