A swimming pool is 5.0 m long, 4.0 m wide and 3.0 m deep. Compute the force exerted by the water against
(
a. The bottom; and
(
b. Either end. (Hint: Calculate the force on a thin, horizontal strip at a depth h, and integrate this over the end of the pool.) Do not include the force due to air pressure.

For the answer to the question above, ater weights 1000kg per meter cubed. the volume of the pool is part A is 5*4*3 = 60 meters cubed 
60*1000 = 60 000kg. the force from this is m*g = 60 000 * 9.81 = 588kN 

part B: 
volume: 4*4*3 = 48 meters cubed 
48 * 1000 = 48000kg 
F = 9.81*48000 = 470kN
I hope this helps.
