The cruise ship Oasis of the Seas has a gross weight of approximately 220,000,000 pounds. Although pure water has a density of 62.4 pounds per cubic foot, ocean water has a density of approximately 65 pounds per cubic foot. When the Oasis of the Seas travels across the ocean, how many cubic feet of water is displaced by its hull?

By carefully reading the question, we are able to discern from its wording the fact that Oasis of the Seas is not a submarine. Instead, wherever she sails, she is expected to float on the surface of the briny deep.

A floating object displaces water equal to its own weight.

So the Oasis must displace

(approx 220,000,000 lbs)/(65 lbs/ft³) =

approx 3,384,615 ft³ of sea water
