What is the total force on the bottom of a swimming pool 1.6 m by 1.4 m whose uniform depth is 2.0 m?
I also need to solve for absolute pressure, how would I do this?

You have to know the weight density of what is in the pool.

A safe bet is that it's water:). The weight density of water is

In metric, the weight density of water is

h=depth of the pool and A is the area of the bottom.

Force is

Pressure is force per unit area.
