The Great Pyramid of Ghiza was measured in the 1880s by Flinders Petrie as having sides of length 230.25 to 230.4 m, with a mean of 230.355 m. Postulating them as being 250 cubits points to a cubit of about 461 mm and a fathom of about 1.84 m, i.e. very close to today's international nautical mile, the length of 1 minute of latitude. In turn this indicates that the Ancient Egyptians, nearly 5 000 years ago, measured Earth's radius. Read more: http://www.answers.com/main/ntquery?s=cubits&gwp=16

I don’t buy that, any more than I buy the claim that the Giza pyramids were built to mimic the position of some stars in the sky 10s of 1000s of years ago.

Nope. The Egyptians didn’t measure the Earth’s radius; whoever designed the pyramids, did.
