You can put this solution on YOUR website!
224,397,021 miles of the earth is covered with water
source wikipedia, it was in kilometers, but i converted it for you
680000 cubic miles of water, lets go ahead and multiply that by 5280, see how many square miles of 1' deep water that would make...
3,590,400,000
now, lets see how many times that goes into the surface area covered w/water
3590400000/224397021
there would be a 16' rise in the water levels around the world
