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
