Question

The edge of a cube measures 11 m. Find the surface area.

Answer 1

In order to determine the surface area of the cube, use the following formula:

$S=6a^2$

where a is the length of the side of a cube a = 11 m.

Replace the value of a into the formula for S:

$S=6(11m)^2=726m^2$

Hence, the surface area of the given cube is 726m^2
