Question

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

Answer 1

Answer:

The difference between the total and lateral surface areas of the room is 42 square yards.

Step-by-step explanation:

The lateral surface area of an object is the surface area of everything EXCEPT for the top and bottom of the object.

2(6*4.2) + 2(4.2*3.5) = 79.8 square yards

The total surface area of an object is everything INCLUDING the top and bottom of the object.

79.8 + 2(6*3.5) = 121.8 square yards

121.8 - 79.8 = 42 square yards
