Question

Hope you don't mind to answer but uhh lol

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 answer to this question is 42yd^2. This is the difference between the total surface area and the lateral surface area of the net you have shown.

Total surface area: 121.8
Lateral surface area: 79.8

121.8 - 79.8 = 42
