We Can All Fit in Texas

Driving home:
I thought about the population of the world. And of course everyone knows that it something like, 6,403,537,604 people, as of today. That's right, as of Dec 1st there are now 6,403,537,500 too many people on this planet.
But this is only part of what I thinking. The second part deals with the great state of Texas. The amount of land in Texas, that is land not water, is 261914 sq. mi.. So if you convert the square miles in to square feet that gives you approximately 7286028417600 sqf. Because there are 27818400 sqf in a mile. So if we wanted to put all the people in the world inside of Texas, just Texas, each person could be given approximately 1137 sq feet. Could someone check this math. This is crazy. We can all fit in Texas!
We need shirts made.
