# Hydrostatic Force Problem

## Homework Statement

An aquarium 8 m long, 4 m wide, and 4 m deep is full of water. Find the following: the hydrostatic force on one end of the aquarium.

## The Attempt at a Solution

I already found the pressure and force on the bottom of the aquarium...now, my main issue understanding what the question means when it says 'end.' Do they mean one of the side walls? One half of the aquarium? If anyone happens to know what that likely means, that'd be awesome.

What I've tried so far is Density*gravity*L/2*W, which was wrong.

1000*9.8*4*4 = 156800.

Is it just the force on the bottom of the aquarium divided by 2? That almost seems too easy...
