A reservoir has a shape that is approximately rectangular. It is being held by a dam that is $450$ meters wide and extends $16\mathrm{.}6$ km away, with a height of $88$ meters. What is the weight of water being held behind the dam?

$F_g=,N$

What is the average pressure exerted on the dam throughout its height? Use the the pressure at the middle of the dam to find this.

$\frac{?}{\text{b}\text{a}\text{r}}(P)=,Pa$

With this pressure, find the average force exerted on the dam wall.

$F=,N$

What percent is this force compared to the total weight of the water?

$\%$
