It is 10 by 16 feetat the top and 10 by 4 feet at the bottom ∆V=5ft3 Assuming that water has a density of 62.4 pounds per cubic foot, find theweight/force of ∆V and include units.arrow_forwardA trough whose cross-section is a trapezoid, measures 6 meters across the bottom and 8 meters across the top, and is 3 meters deep. If the trough is filled with a liquid of mass density p, what is the force due to hydrostatic pressure on one end of the trough? Write your answer in terms of p.arrow_forwardA tank shown below has vertical ends in the shape of isosceles triangles. Its dimensions are given as L = 9 m, w = 2.3 m, h = 1.9 m. The tank is filled with a fluid of density 867 kg/m³ to a depth of c = 1 m. Assume that the acceleration due to gravity is g = 9.81 m/s² h Find the force exerted on one of the triangular ends by the fluid. Round your answer to at least 3 sig figs.
