A trapezoidal plate, with 9m and 5m bases and 3m height, is submerged vertically in a tank of water so that its top is 2m to the water surface (as figure below). Calculate the hydrostatic force against one side of the plate. (Water mass density ρ = 1000 kg/m3, and g = 9.8 m/s2).

Please help me with this. My answer is 690900.
