Acube is shown below. what is the lateral surface area of the cube?

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!

no this is a nonlinear negative

the answer is b
