The surface area of the Earth is:
4 * pi * r^2
= 4 * pi * (6378.1 km)^2
= 511201962.3 square km
And, since there are 3280.839895 feet per km, there are 10763910.42 square feet per square km.
So, the square footage of the earth (assuming a spherical shape, not ellipsoidal) is:
511201962.3 * 10763910.42
= 5.502532127 x 10^15 square feet
That's approximately:
5,502,532,127,000,000 square feet
Which is read, "Five quadrillion, five hundred two trillion, five hundred thirty-two billion, one hundred twenty-seven million square feet".
