I think mathematically everyone will fit in Texas on an acre of land. I’d have to review the numbers again too. It blows people’s minds, they still won’t believe it.
Assume Texas is perfectly flat and featureless...
Texas (square miles) 261,797
Square mile in square feet 27,878,400
Texas (square feet) 7,298,481,484,800
Approximate population, H. sapiens (Planet Earth only) 7,000,000,000
Square feet of Texas per individual H. sapiens, divided equally 1,043
Exact measurement of each side of square territory 32.2899397973159
