Zach is building a new shed shaped like a square prism. He wants the height of the shed to be 7 feet less
than the length and width. If he needs the volume to be as close as possible to 722 ft', what should the
length be? Round to the nearest foot.
For the equation, let y be the volume of the shed and x be the length of the shed. Then fill in the table to
to find the dimensions with closest possible volume.
The volume equation isy -

|x (ft) y (4)
feet is the closest possible width.
