For Monica 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 9ft high find the surface area of the room that you are going to paint including the floor and ceiling
To find the total surface area of the room that needs to be painted, we first find the area of each wall.
1. The two shorter walls (15 ft x 9 ft) will have the same area: 15 ft x 9 ft = 135 sq ft x 2 = 270 sq ft
2. The two longer walls (20 ft x 9 ft) will also have the same area: 20 ft x 9 ft = 180 sq ft x 2 = 360 sq ft
3. The ceiling (20 ft x 15 ft) will have an area of: 20 ft x 15 ft = 300 sq ft
4. The floor (20 ft x 15 ft) will also have an area of: 20 ft x 15 ft = 300 sq ft
Now, we add up all these areas to find the total surface area that needs to be painted:
270 sq ft (short walls) + 360 sq ft (long walls) + 300 sq ft (ceiling) + 300 sq ft (floor) = 1,230 sq ft
So, the total surface area of the room that needs to be painted, including the floor and ceiling, is 1,230 square feet.
