For Monica's 14th birthday, she wants to makeover 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, including the floor and ceiling.

Answer 1

[AI-generated answer — Bot GPT 3.5]

Surface Area = 2(20 x 15) + 2(20 x 9) + 2(15 x 9)

Surface Area = 2(300) + 2(180) + 2(135)
Surface Area = 600 + 360 + 270
Surface Area = 1230 square feet

Therefore, the surface area of Monica's room that needs to be painted, including the floor and ceiling, is 1230 square feet.
