A cubic mile of seawater contains approximately 0.004 parts per million of gold, which translates to about 0.000006 grams of gold per liter. Given that there are about 4.2 billion liters in a cubic mile, this results in roughly 7,000 grams, or about 15.4 pounds, of gold in a cubic mile of seawater. However, extracting this gold is currently not economically viable due to the low concentration.
It depends on the material used for the sweater.
5280 ft x 5280 ft x 5280 ft x 62.4 lbs per square ft = 9,185,152,204,800 lbs
1 mile = 5280 ft1 Cubic Mile = 5280x5280x5280= 147197952000 cubic Feet
a cubic ton
I once had a book about the ocean that claimed that there was 38 pounds of gold in one cubic mile of seawater. You could figure 1 cubic kilometer from here but you are still left with the validity of the claim of the book and even worse, my memory of that book. Still, something to play with.
