Math Challenge Problem

The Math Challenge problem has returned to UNC's School of Mathematical Sciences! This is a problem that everyone is welcomed to try their hand at. New problems twice a month.

January Challenge

Spider Cube

A spider stands on one corner of a solid wooden cube. On the opposite corner sits a delicious fly. The spider can scurry across the cube's surface at a speed of 3 inches per second. The fly needs 10 seconds before he can fly away (presumably to deice his wings).

The Challenge: What is the smallest cube for which the fly can escape in time?
