An ant is sitting on the vertex of a cube. What is the shortest path along which it can crawl to the diagonally opposite vertex? The ant stays on the *skin* of the cube all the time.

Here is a solution presented by the students in class:

- Open the cube (flatten it up)
- Join the two points by a straight line on the surface of the flattened figure
- Then re-make the cube again
