Mr. Guest decides to quit teaching and instead work at the post office. Unfortunately, he is lousy at his new job and gets demoted to the box cutter division. His boss tells him that he must make a box whose base is 3 times longer than the width of the box. If the box volume has to be 50 cubic feet then what are the minimum dimensions for the sides of the box?
w=(20/3)^1/3=1.88
