A 9 foot tall wall is next to a rectangular tank

that is 7 feet long, 8 feet wide and 6 feet tall.

The tank is full of a liquid that has a density

of 60 pounds per cubic foot.



Represent the amount of WORK done to

lift (pump) the top 2 feet of liquid to the top

of the wall as an integral.


Work = ∫ab\displaystyle {\int_{{\text{a}}}^{{\text{b}}}}   dx

a =

b =

Then evaluate the integral. Work = f∞t⋅pounds\displaystyle {f}\infty{t}\cdot{p}{o}{u}{n}{d}{s}
