Question

A cube has a volume of $216c{m}^3$. What is the length of side of the cube?

• A. $5cm$
• B. $8cm$
• C. $6cm$
• D. $7cm$

Answer 1

The correct option is C $6cm$

Given:
Volume of cube: $V=216c{m}^3$.

Volume of cube is given by:
$V=a^3$
where $a$ is the length of the side of cube.

$V=216c{m}^3$
$a^3=2^3\times 3^{3}c{m}^3$
$a^3=6^{3}c{m}^3$
$a=6cm$

So, side length = $6cm$
