A) If a square ship 350'x150' sit 16' deep in the salt water (d=1.06g/ml), what is the mass of the ship in tons?B) If cargo is added so that the ship now sits 20' in the water, how many pounds of cargo was added? Please explain how come to the answer. The answer is suppose to be around 28,000 tons.
