A rectangular swimming pool is 4 feet deep, 75 feet long, and 25 feet wide. It is completely filled with water.

a. What is the hydrostatic force on the bottom of the pool?

b. What is the hydrostatic force on the shorter wall of the pool?

c. What is the hydrostatic force on the longer wall of the pool?

d. How much work is required to pump all the water out of the pool (i.e., up to the top of the pool)?

As far as a. goes, I think it is the integral of (62.4 lbs/feet

^{3})(75)(25)(4-y

_{i}) as goes from 0 to 4, but I am far from confident. And the rest has me baffled.
