Question 940771: The water on earth can be split into salty seawater and fresh river water. Humans animals and plants can only drink freshwater. But only 2.6% of all the water on earth is fresh. 1.82% of this water is locked away in ice sheets and glaciers.
This leaves only 0.78% available which is safe for us to drink.
If there is 1,386,000,000km3 (cubed) of water on the earth how much is safe to drink?

--> 1.386e9 * 0.78/100
= 1.386e9*7.8e-3
= 1.386*7.8e6
= 10.811e6
= 10,811,000 km^3
