To put this in perspective, 692 miles is about the distance from New York City to Charleston in South Carolina. This box would hold a tremendous volume of water, 332.5 million cubic miles in size to be exact. Just 1 cubic mile of water is equal to about 1 trillion gallons of water. Now that is a lot of water!! Of this water approximately 97% of it is ocean salt water. The remaining 3 % of water is freshwater found in ice, rivers, and underground, with the majority of earth's freshwater is stored in ice. Very little freshwater is available for human purposes like drinking water and irrigation.
