OK, here I got a little crazy. This is the diagram for a 3-D entrelac shape I knitted for my first nephew. It knits up to be the shape of a cube surrounded by six other cubes. That shape has 5 time 6 equals 30 faces. Each face is made up of 4 half-squares, which gives a total of 60 squares.
It would definitely make more sense with a picture of the finished result. I'll work on that.
