How many square feet is the earth?

Answer 1

If earth has 196,940,400 square miles of total surface area (land and water) as most of the websites indicate (some websites say 196,935,000 square miles). Multiply by 5,280 squared: 5,490,383,247,360,000 square feet (Or if the other websites are correct: 5,490,232,704,000,000 square feet) In any event, a little less than 5-1/2 quadrillion square feet. ===== As an aside, the largest body in the solar system (the Sun): Approximately 864,000 miles in diameter according to most sources. Comes out to 2,345,184,368,640 square miles of _extremely_hot_ 'surface' area. Or, a little more than 2-1/3 trillion square miles. Square feet? Try 65,379,987,902,693,376,000 square feet, (just as hot). Or, a little more than 65-1/3 quintillion square feet. Wouldn't be very much fun to count. Ugh! Get me some water!
