If you divided the square feet in Texas by the world's population, what would be the square foot area available per person?

Texas land area is: 261,232 square miles (http://www.texasalmanac.com/topics/facts-profile)

1 square mile = 640 acres: 261,232 x 640 = 167,188,480 square acres

1 acre = 43,560 square feet: 167,188,480 x 43,560 = 7,282,730,188,800 square feet

World Population: 7,000,000,000 (https://en.wikipedia.org/wiki/World_population)

Thus: 7,282,730,188,800 square feet divided by 7,000,000,000 people = 1040.39 square feet per person
