The closer to a square you can make the shape, the more area it will take up. Bigger area on one side equals bigger volume. So make each side 6.25 inches long

here is the easy answer.
the gratest volume will be when the
area of rectangle is maximum, because
the height is 7" constant.
the area of a rectangle is max when
width and length are equal,so:
L=W=25/4=6.25"

Hi. I think 6.25" on a side. Volume equals 273.4375 cubic inches.

everyone is saying 6.25 for each side
but then it will be a square since each side is equal
and not a rectangle
