Homework Help: Force exerted on tank

  1. Sep 10, 2007 #1
    1. The problem statement, all variables and given/known data

    An aquarium tank is 100 cm long, 35 cm wide, and 40 cm deep. It is filled to the top.
    What is the force of the water on the bottom (100cmX35cm) of the tank?
    What is the force of the water on the front window (100x40) of the tank?
    2. Relevant equations
    this where i am unsure is it just f=mg? or F=pA. how do i get p?

    3. The attempt at a solution
    tried the equations above and got nowhere. also tried to solve using the density of water to find the mass but got nowhere so please advise thanks.
