## Homework Statement

## Homework Equations

dp/dz=-ρg

p=ρgh

## The Attempt at a Solution

I've found the density at depth 3m using ρ=ρ

_{0}+kh, which gave me 1060kgm

^{-3}. I then put this value into ρgh to get 31195.8Pa which seems to be ≈+1000 off the answer.

What is the correct mathematical way of solving this as I am not quite sure how to form the equation for variation of pressure using that.
