Question

If the volume of a cube is $64$ $c{m}^3$, then its surface area is _____

• A. $96$ $c{m}^2$
• B. $16$ $c{m}^2$
• C. $24$ $c{m}^2$
• D. $72$ $c{m}^2$

Answer 1

The correct option is A $96$ $c{m}^2$

Given, volume of cube $=64$ $c{m}^3$

We need o find surface area of cube

Volume of cube $=a^3=64$
$\therefore a=4$ $cm$
Surface area $=6a^2=6\times 16=96$ $c{m}^2$
