The building has 42 storage units that are a total of 5040 square feet. Twenty of the units are 8 by 4 feet each. If the remaining units are all the same size, what is the area, in square feet, for one of the remaining units?
How many square feet are in each of the twenty units? ** 8 * 4 = <<8*4=32>>32 square feet
How many square feet are in the twenty units in total? ** 20 * 32 = <<20*32=640>>640 square feet
How many square feet are in the remaining units? ** 5040 - 640 = <<5040-640=4400>>4400 square feet
How many units are remaining? ** There are 42 - 20 = <<42-20=22>>22 remaining units
How many square feet are in each of the remaining units? ** 4400/22 = <<4400/22=200>>200 square feet
What is the area, in square feet, for one of the remaining units? ** One of the remaining units is 200 square feet.
