Question 588Deck Safety70% to pass
When water is used to fight a fire on board a ship, the effect of the weight of the water must be taken into account. How much sea water will increase the weight displacement by one ton?
AI Explanation
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.
