Question

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

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

Answer 1

The correct option is C 6 cm

Given,
Volume of cube: $V$ = 216 cm${}^3$

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

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

$\therefore$ Side length = 6 cm
