Question

A fly is walking along the edges of a10cm cube. The fly never walks along any edge more than once. The greatest distance, in centimeters, that the fly can walk is?

Answer 1

Is there more information to it

Answer 2

I traced it out in this picture I drew, and it looks like the fly can walk along 9 of the 12 edges, without repeating any edges.
Try it for yourself, see if you can get more than 9. You should be able to work it out if you can visualize the cube and keep track of the edges.

Answer 3

yes
