Third number: I needed a place to sit, so I built a couch. It isn't very comfortable. I *
built it by putting two boxes together. The first box is 6 feet long, 2 feet wide, and
2 feet high. The second box is 6 feet long, 2 foot wide and 4 feet tall. To make the
couches strong, I filled the two boxes with stone cubes that were 1 cubic foot
each. How many stone cubes did I use?
