Question 588 Deck Safety

The correct answer is C) 35 cubic feet. The reasoning behind this is that 1 ton of seawater is equivalent to 35 cubic feet. This is based on the density of seawater, which is approximately 64 pounds per cubic foot. Therefore, to add 1 ton of weight to a ship's displacement, it would require 35 cubic feet of seawater. The other options are incorrect because: A) 64 cubic feet would be too much, as that would be equivalent to more than 1 ton; B) 500 liters is approximately 17.6 cubic feet, which is less than the 35 cubic feet required; and D) 100 gallons is approximately 13.3 cubic feet, which is also less than the correct amount.
