Question

The volume of a cube is 64 cm${}^3$, then find the surface area.

Answer 1

Let “$a$” be the side of the cube
${\text{Given that, the volume of cube is 64 cm}}^3$
$\text{It means that}{a}^3=64{\text{cm}}^3$
Hence, $a$ = 4 cm
$\text{Therefore, the surface area of a cube}=6a^2$
$=6\times 16$
$=96c{m}^2$
