A semisubmersible displacing 700,000 cubic feet while floating in sea water (64 pounds per cubic foot) weighs _______________.
AI Explanation
The correct answer is C) 20,000 long tons.
To calculate the weight of the semisubmersible, we need to use the formula for displacement, which is the weight of the water displaced by the vessel. The formula is: Displacement (in long tons) = Volume (in cubic feet) x Density of water (in long tons per cubic foot).
Given that the semisubmersible displaces 700,000 cubic feet while floating in sea water (64 pounds per cubic foot), we can calculate the displacement as follows:
Displacement = 700,000 cubic feet x (64 pounds per cubic foot / 2,240 pounds per long ton) = 20,000 long tons.
The other options are incorrect because they do not correctly apply the formula for displacement or use the appropriate density of sea water.
