A large aquarium has the triangluar viewing window shown below. The vertices are at (−16, 0) and (16, 0) and (0, 8). The water surface is at y = 21 (shown by the blue line). All distances are in feet. The weight density of water is 62.5 lbs/ft∧3. Find the hydrostatic force on the window. (graph not to scale) lbs
