Question

An above-ground swimming pool is 5 feet long, 4 feet wide, and 3 feet deep and is shaped like a rectangular prism. A rectangular prism has a length of 5 feet, height of 3 feet, and width of feet. If you use a net to find the amount of material used to make the pool, what faces are included in the calculation?

Answer 1

First answer is 1

Second is 2

Third is 2

Answer 2

the faces representing the sides and bottom of the pool are included

Explanation:

Obviously, there is no pool material covering the top of the pool. Rather, it is "an open-top box", so the area of the faces of the box does not include the area of the top. The five faces other than the top face are included.
