Howard is laying an oak wooden floor in his house. The measurements of the floor are 14.5 feet by 40 feet. The wood is packaged in boxes. Each box will cover 18 square feet. How many boxes of wood must be purchased to cover the floor?

First you need to find the area of the floor to know how much wood you need

Area=lengthxwidth, so A=40x14.5 which equals 580 square ft

With a floor that's 580 square ft and the boxes cover 18 Sq ft each then all you have to do is 580/18 = 32.222 and because you can't buy. 222 of a box you need to round up to 33 boxes
