Robert - I agree with Angela.  While I didn't check any of the calculations, your step by step explanation was clear, crisp, and even humorous at one point.  Nice job.

8340 Meters? So 8 km which is about 4.97 miles. Out of approximately 3 lbs of copper, you are saying you could make 5 miles of 34 gauge wire?

As amazing as that sounds, it is true. The key to understanding this is to understand that 34 gauge wire is quite small, its diameter is only about 120% that of a human hair, after all.
