Question 294745: The earth has a total surface area of approximately 5.1x10^14 = 510,000,000,000,000 sq. meters. Seventy percent of this surface area is rock, ice, sand, and open ocean, Another 8% of the total surface area is tundra, lakes, streams, continental shelves, algal beds, reefs, and estuaries. We will consider the remaining area suitable for growning food and for living space.
