## Homework Statement

A lobster tank in a restaurant is 8 ft long by 7 ft wide by 2 ft deep. Find the water force on the bottom and on each of the four sides. The density of water is 62.4 lb/ft3.

## Homework Equations

Pressure = density * gravity * height

Force = Pressure * Area

## The Attempt at a Solution

Force on the bottom = density * gravity * height * area

= 62.4g(2)(56)

It is asking for the Force in Lb

In my book we used integrals for this type of problem but I don't see the point..

I'm trying to put the answer in webassign.

For the sides would it be the same equation without gravity, as gravity is only in play in the up and down directions?
