After solving this problem, Juan was very clever and invented the following strange question:
A building, in the shape of a rectangular prism with a square base, has on its top a radio tower. The
building is 25 times as tall as the tower, and the side-length of the base of the building is 100 feet less than
the height of the building. If the building has a volume of 2 million cubic feet, how tall is the tower?
