Problema Solution
A room with width w, length l, and height h with four walls needs to be painted. Write a formula for the area that needs to be painted not accounting for doors and windows.
Answer provided by our tutors
The area that is on the four walls:
four walls: 2wh+2lh
If we wanted to paint the ceiling and floor, we would write:
ceiling and floor: 2wl
Therefore, the total room would be:
Total=2wh+2lh+2wl
or
Total=2(wh+lh+wl)
