Paths on a cube
An ant that walks on a cube, sets off from the centre of one face and walks straight on towards one of the adjacent squares, covers a ring of four squares before arriving at the starting point. This can be easily seen on a model of a cube, but the path is less evident on a drawing of a net. In the figure we see two of these paths, but there's a third path.
