Weekly Problem 48 - 2008

Stage: 3 Short Challenge Level: Challenge Level:1

The ant climbs up the cube (adding $1 \; \text{cm}$), walks across the top of the cube on the same path as he would have done if the cube wasn't there, then climbs back down to the table (adding another $1 \; \text{cm}$), so the total extra distance is $2 \; \text{cm}$ .

This problem is taken from the UKMT Mathematical Challenges.
