There are 3,615,122 square miles in America. If you could space all of us Americans out equally across the whole country, assuming that you could place some people on the sides of mountains and others in the middle of factories, but assuming that all Americans had to be the same distance apart, we would be 645 feet away from each other. That’s about one-half the length of a city block. We each would have 415,388 square feet, which is approximately 10 acres or the amount of land covered by 500 apartments.
