Make 2 identical strawberry rhubarb pies. Cut one into FOUR equal pieces. Cut the other into TEN equal pieces. If you give out a piece from the one cut into 4 pieces, and a piece from the one cut into 10 pieces, which piece will be larger? The first pie is cut into fourths, and the second is cut into tenths.
It will make two squares.
21 cuts required to cut a cube into 504 identical pieces.
