Right - the circumference of the Earth around the equator is approximately 25,000 miles. Assuming it were possible, it would take 25,000 miles of cable to lay a cable completely round the equator flat to the Earth. If it was then required to raise the cable to run completely round at the top of 10 foot high poles all the way round the equator approximately how much more cable would be required?
