I want to paint two rooms. One room has 3 walls that are 12 feet high and 16 feet wide. The other room has 2 walls that are 12 feet high and 12 feet wide and 2 walls that are 12 feet high and 14 feet wide. Assume I am only applying one coat of paint. Each can of paint will cover 600 sq ft. How many cans of paint do I need to buy?
