If the entire population of the United States forms a human chain by holding hands, how many times can such a chain be wrapped around the earth's equator? I don't have any additional info other than round to the nearest integer.

Well, the estimated population right now from the census bureau is 300,960,855 I'd figure that the average reach from hand to is would be about 5 to 5.5 feet. You can figure it from here.

Let's assume an average 5 ft "hand-holding" span. The population of the U. S. just passed 300,000,000, so you have 300,000,000*5/5280 = 284,090,909 miles. The circumference of the earth at the equator is 24,901.55 miles, so 284090909/24,901.55 = 11,408 times.

I get 285 assuming 6 billion time 6 feet each
