1. The problem statement, all variables and given/known data A vertical rectangular dam of width 25m contains water in a reservoir of depth 15m. What is the overall force exerted on the dam by the water? 2. Relevant equations P=F/A .... F=PA P = pgh 3. The attempt at a solution I'm really not sure about this one to be honest. I tried finding the Pressure (1000*9.807*15) and then multiplying that by area (15*25) but that doesn't give the right answer. Any tips would be much appreciated.
