## Depth, Pressure, and Force

1. The problem statement, all variables and given/known data

A large aquarium of height 5.00m is filled with fresh water to a depth of 2.00m. One wall of the aquarium consists of thick plastic of 8.00m wide. By how much does the total force on that wall increase if the aquarium is next filled to a depth of 4.00m.

D= density

2. Relevant equations

p = P0 + Dgh

F=PA

3. The attempt at a solution

?

Not supposed to use Integration.

Okay. How about using the average pressure exerted on the wall instead?
