The room is a cube with edge length 11 feet including the ceiling in the floor how much surface area must be painted

1 answer:

6 0

Answer: 726cm squared

Surface area is the area of all the faces added together.

If the area of one face is 11x11=121

Because it is a cube and it has six faces with the same surface area we do 121x6=726 to give us the total surface area.
