For Monica's 14th birthday, she wants to make over her bedroom. The first phase in the bedroom makeover is painting her room. If Monica's room is 20 ft long, 15 ft wide, and 9 ft high, find the surface area of the room that you are going to paint. (Pretend that you are painting the floor and ceiling as well)(1 point)
