Problem # $1$: A gate in an irrigation canal is constructed in the form of a trapezoid $6m$ wide at the bottom, $18m$ wide at the top,

and $2m$ high. It is placed vertically in the canal so that the water just covers the gate. Find the hydrostatic force

on one side of the gate.

Note that your answer should be in Newtons, and use $g=9\mathrm{.}8\frac{m}{s^2}.$
