The PackUUp Moving Company uses several different size boxes,but the boxes all have the same meaurements on the top andbottom so they'll stack neatly on top of one another.The only differences between the boxes is their heights: some are three feet high, some are two feet high, and some are one foot high. If the moving company made stacks three boxes high, how many different stacks could be made?
Note that this stack of boxes on the left...
3 is the same as
