Question

Antoine is using special blackboard paint to paint a blackboard on a classroom wall. The wall is 8 meters long and 3 meters tall. One can of blackboard paint covers 6 square meters. How many cans of blackboard paint does Antoine need?

Answer 1

First we have to find the amount of area the paint needs to cover. We do this by doing 8*3=24. Next we divide 24 by 6 to find how many cans are needed. Therefore, the answer is 4 cans of paint.
