Because over two thirds of the Earth's surface is naturally covered in water.
Where r is the radius of the Earth, and pi = 3.14 (2 decimal places). So, it's 4 thirds multiplied by pi multiplied by the cubed radius of the Earth (6378.1Km average)The best estimate for the Earth's volume is about 1083210000000 cubic km
oceans freshwater and lakes and streams cover 2/3 of earth
97% of water on the Earth is salt water, and only 3% is fresh water of which slightly over two thirds is frozen in glaciers and polar ice caps.
Archimedes accurately estimated the value of pi. He was also the Greek inventor that created the compound pulley and first device used for extracting water from below the surface of the earth as well.
