conversations.value: I'm completely lost with this math problem: John builds a box.  The box is 26 inches by 26 inches by 14 inches.  The walls are 1 inch thick on each side.  How much is the internal volume in cubic feet?
  Can you give me a hand?

conversations.value: The walls take away 2*1=2 inches from each dimension
  So the longer sides are 26-2=24 inches
  That is 24/12=2 feet
  The smaller dimension is 14-2=12 inches
  That is 12/12=1 foot
  So the internal volume is 2*2*1=4 cubic feet
