The floating platform shown is supported at each of its four corners by a hollow sealed cylinder 1 m in diameter. Each cylinder weighs 1.2 kN per meter of length. If the length of each cylinder L is as shown in the diagram below, and the platform floats 0.50 m above the water surface, what is the weight of the floating platform? Assume that the specific weight of the water (brackish) is 10,000 N/m3. The platform is square in plan view.
