Problem Statement

The rectangular parallelepiped (box) PP has some special properties. If one dimension of PP were doubled and another dimension were halved, then the surface area of PP would stay the same. If instead one dimension of PP were tripled and another dimension were divided by 33, then the surface area of PP would still stay the same. If the middle (by length) dimension of PP is 11, compute the least possible volume of PP.
