Lucille is painting her room. Two of her walls are 3 meters wide and 2 meters tall. The third wall is 5 meters wide and 2 meters tall. The final wall is 4 meters wide and 2 meters tall. If each can of paint covers 2 square meters, how many cans of paint does Lucille need?
How many square meters does each wall cover? ** For the first set of walls, each wall covers 3 meters wide * 2 meters tall = <<3*2=6>>6 square meters.
How many square meters does each wall cover? ** There are two of these walls, so this becomes a total of 6 meters * 2 walls = <<6*2=12>>12 square meters.
How many square meters does the third wall cover? ** The third wall covers 5 meters wide * 2 meters tall = <<5*2=10>>10 square meters.
How many square meters does the final wall cover? ** The final wall covers 4 meters wide * 2 meters tall = <<4*2=8>>8 square meters.
How many square meters does the paint need to cover? ** So in total, the paint needs to cover 12 + 10 + 8 = <<12+10+8=30>>30 metres.
How many cans of paint does Lucelie need? ** Since each can covers 2 meters, Lucille needs 30 meters / 2 = <<30/2=15>>15 cans of paint.
