Question

The net below shows the dimensions of Michelle’s living room. She is going to put wallpaper on the living room walls.

What is the difference, in square yards, between the total and lateral surface areas of the room?

Answer 1

The correct answer for this question is C - 42 yards squared.

The reason for this is that the total surface area (121.8yd^2) minus the lateral surface area (79.8yd^2) equals 42yd^2.
