Fluid at rest

  1. Feb 11, 2007 #1
    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.

    The problem probably wants you to start by writing an equation for the pressure vs depth. Can you do that...?

    Btw, we have a homework section...

    the answer is on that page although it's stupid since they haven't explained what they did and why.
