Right order of magnitude. There's 1.33×10^9 km^3 water in the ocean. .510×10^9 km^2 surface area on the earth. .292 of the surface is land. If I did the math right that's about 29,000 feet.
- yborg 9y agoSo Waterworld got something right.
- bbgm 9y agoAs high as Mt. Everest. Crazy!!
- ilyagr 9y agoIt's actually 2.7km, approximately 8600 feet.
- ilyagr 9y agoIf your numbers are right, the quotient is about 2.7km which is 8555 feet.
- caseymarquis 9y ago1.33/.51/.292 is about 8.9km. You're spreading the ocean over the surface of the entire earth instead of just the continents. Average ocean depth is 12,000 feet, and there's less land than ocean, so the answer must be greater than 12,000 feet.
