A gate in an irrigation canal is in the form of a trapezoid 3 feet wide at the bottom, 5 feet wide at the top, with the height equal to 2 feet. It is placed vertically in the canal with the water extending to its top. For simplicity, take the density of water to be 60 lb/ft cubed. Find the hydrostatic force in pounds on the gate.(adsbygoogle = window.adsbygoogle || []).push({});

I am having problems setting this problem up. It looks like its really easy but I am just not sure how to start it.

I know F = density x gravity x area x depth
