conversations.value: The north and south walls are 80 square feet each because 10 x 8 = 80
  The east and west walls are 40 square feet because 5 x 8 = 40
  The south and north walls total 160 square feet because 80 x 2 = 160
  The East and west walls total 80 square feet because 40 x 2 = 80
  All the walls total 240 square feet because 160 + 80 = 240
  He will need 12 gallons of paint because 240 / 20 = 12
  It will cost $144 because 12 x 12 = 144
