conversations.value: Mark builds an apartment that is 16 by 10 feet.  There are 6 rooms in total.  All the rooms are the same size except the living room which is as big as 3 other rooms.  How big is the living room?
  Can you solve this problem?

conversations.value: Total square footage is 16*10=160 square feet
  
  There are 3+3=6 rooms
  6-1=5 of them are the same size
  If x is the size of the normal room then the square footage of all rooms is 5x+3x=8x
  So each room is 160/8=20 square feet
  So the living room is 20*3=60 square feet
