A postal service requires that

Question

A postal service requires that any box sent by priority mail have length plus girth (distance around) totaling no more than 101 in. One volume that meets this condition is contained by a box with a square end 15in on each side. What is the length of the box? What is the volume?

Answer 1

The length must be no more than 71" (101 - 30) = 71.

If the length is exactly 71, then volume = 225 * 71
