Mya's bedroom is in the shape of a rectangular prism 15 feet long, 12 feet wide, and 10 feet high. It has no windows. Mya wants to paint all four walls (including the door) and the ceiling. What surface area will she paint?
I am not american, so I don't know if this is correct or now. You times 10*15 to get the surface area of one wall. Then you times that by 4 to get four walls. I think the answer is 600 ft
