Question

If the lateral surface area of the cube is 5476 m${}^2$ then find the side of the cube.

Answer 1

Lateral surface area of the cube $=5476m^2$
Lateral surface area of the cube $=4a^2$
$5476=4a^2$
$a^2=\frac{5476}{4}$
$a^2=1369$
$\sqrt{a^2}=\sqrt{1369}$
$a=37m$
Hence, the side of the cube is 37 m.
