A water tower is filled with fresh water to a depth of 6.38 m. What is the water pressure at a depth of 3.96 m?

take a column of area A, height h.

The weight of that column is density*volume*g=density*Ah*g

= 1000kg/m^2*9.8N/kg*A*(3.96)

pressure= weight/A

I measured depth from the top, I assume the writer here had that in mind.

I'm confused about what A should be then? Is that what I'm solving for? I thought I was solving for pressure?

A cancels top and bottom
