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 what is the surface area of the room that she is going to paint including the floor and ceiling. In square feet
First, we need to calculate the surface area of each wall:
- Two walls that are 20 ft long and 9 ft high: 2 * 20 ft * 9 ft = 360 sq ft
- Two walls that are 15 ft wide and 9 ft high: 2 * 15 ft * 9 ft = 270 sq ft
- The floor area: 20 ft * 15 ft = 300 sq ft
- The ceiling area: 20 ft * 15 ft = 300 sq ft
Now, adding up all the surface areas:
360 sq ft + 270 sq ft + 300 sq ft + 300 sq ft = 1230 sq ft
Monica will need to paint a total surface area of 1230 square feet for her bedroom makeover.
