Question

A cube is shown below.What is the lateral surface area of the cube?

Answer 1

The lateral surface area is the surface area of the cube excluding the base and the top, which would make 4 square planes.

First we can find the area of a square plane:

4 1/2 x 4 1//2

=20 1/4 ft²

We can then multiply the area of plane by 4:

20 1/4 x 4

=81 ft²

Therefore the answer is 81 ft².

Hope it helps!
