Area of a lake is 28958 square miles and depth is 207 ft.If there is 35 gram of salt per liter of water, how many grams of salt is there?

I would convert 28958 mi^2 to cm^2 and 207 ft to cm. Then cm^2 x cm depth = volume of lake in cc. Divide by 1000 to convert to L.

35 g NaCl/L x #L = grams NaCl.
