Question

Find the lateral surface area of a cube of side $8cm$.

Answer 1

Find the lateral surface area of the cube.

Given that, side $\left(a\right)$ of the cube $=8cm$

The lateral surface area of the cube of side $\left(a\right)$ $=4a^2$

$=4\times 8^2$

$=4\times 64$

$=256c{m}^2$

Hence, the lateral surface area of cube is $256c{m}^2$.
