Question

A room is 12 feet long, 14 feet wide, and 11 feet high. The walls, ceiling, and floor are all to be painted the same color. How many square feet must be covered with paint?

Answer 1

Answer:

908 feet²

Step-by-step explanation:

To paint walls, we will be looking for surface area.

      Since this is a room and we have three measurements, we can assume there will be the floor, the ceiling, and four walls. This means we will be looking for 6 sides in total.

-> See attached for a diagram I made of the sides we need

-> Keep in mind opposite pairs of walls will be the same, and the floor and ceiling will be the same.

     

      We end up with the following sides:

          11 * 12

          11 * 12

          11 * 14

          11 * 14

          12 * 14

          12 * 14

      We can simplify this to the following:

(2(11 * 12)) + (2(11 * 14) + (2(12 * 14) = 908 feet²

908 feet² must be covered with paint.
