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, including the floor and ceiling

Answer 1

To find the surface area of the room that needs to be painted, we need to add up the area of each of the six sides.

Floor area: 20 ft. x 15 ft. = 300 sq. ft.
Ceiling area: 20 ft. x 15 ft. = 300 sq. ft.
Front and back wall area: 2 x 20 ft. x 9 ft. = 360 sq. ft.
Two side wall areas: 2 x 15 ft. x 9 ft. = 270 sq. ft.

Total surface area to be painted: 300 + 300 + 360 + 270 = 1230 sq. ft.

Therefore, Monica needs to paint a surface area of 1230 square feet for her bedroom makeover.
