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 20ft long 15 ft wide and 9 ft high find the surfyarea 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 find the total area of all the walls, floor, and ceiling.

First, find the area of the 4 walls:
2(20ft x 9 ft) + 2(15ft x 9ft) = 360 sq. ft

Next, find the area of the floor and ceiling:
20ft x 15ft + 20ft x 15ft = 600 sq. ft

Now, add the area of the walls, floor, and ceiling together:
360 sq. ft (walls) + 600 sq. ft (floor and ceiling) = 960 sq. ft

Therefore, the total surface area of the room that needs to be painted is 960 sq. ft.
