Answer: 160 revolutions.
Using the BrainBashers E-commerce solution, James ordered a fishing rod, priced at $3.56.
Unfortunately, James is an fisherman who lives in a very remote part of Puzzleland and the import rules there forbid any package longer than 4 feet to be imported.
The fishing rod was 4 feet and 1 inch, just a little too long, so how can the fishing rod be mailed to James without breaking the rules? Ideally James would like the fishing rod to arrive in one piece!

Hint: The fishing rod does end up in a real box.
One solution is to use a box which measures 4 feet on all sides, the fishing rod will fit within the diagonal of the box with room to spare.
