conversations.value: John fills a 6 foot by 4 foot pool that is 5 feet deep.  It cost $.1 per cubic foot to fill.  How much does it cost to fill?
conversations.from: assistant
conversations.value: The pool has a base of 6*4=24 square feet
  So its volume was 24*5=120 cubic feet
  So it cost 120*.1=$12 to fill the pool
