One company makes inflatable swimming pools that come in four sizes of rectangular prisms. The length of each pool is twice the width and twice the depth. The depth of each pool is a whole number from 5 to 8 feet. If the pools are filled all the way to the top, what is the volume of each pool? V = ( × 5) × 5 = cu ft V = ( × 6) × 6 = cu ft V = ( × 7) × 7 = cu ft V = ( × 8) × 8 = cu ft
