Fly's schedule (Posted on 2015-10-15) Difficulty: 3 of 5
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).

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