Question 2532 Deck Safety

The correct answer is C) 2.60 feet. The formula to calculate the approximate GM (metacentric height) is: GM = (T^2 * D) / (0.8542 * B^2) Where: T = Rolling period (in seconds) D = Displacement (in tons) B = Beam (in feet) Plugging in the given values: T = 15.0 seconds D = 10,000 tons B = 55 feet GM = (15.0^2 * 10,000) / (0.8542 * 55^2) GM = 2.60 feet This is the correct answer based on the formula for calculating approximate GM using the vessel's rolling period, displacement, and beam. The other options are incorrect because they do not match the result obtained from the GM formula.
