Determine the number of sheets of plywood needed to lay the subfloor of a building that measures 24' wide and 64' long. what is the total square footage of these pieces?
The 24' dimension is 6 times the 4' dimension of a 4×8 ft piece of plywood. The 64' dimension is 8 times the 8' dimension of a 4×8 ft piece of plywood.
Hence, it will take 6×8 = 48 pieces of plywood to cover the floor.
The area of the floor is the product of its dimensions:
