(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A test tube standing vertically in a test-tube rack contains 2.5 cm of oil (ρ=0.81 g/cm^{3}) and 6.5 cm of water. What is the pressure exerted by the two liquids on the bottom of the test tube?

2. Relevant equations

P=ρgh

ρ=density of a fluid=mass/volume

g=gravity

P=F/A

3. The attempt at a solution

I don't know how to start this problem. I think I'm supposed to be using density of a fluid, I'm not sure. If that's the case, I know density of water=1000 kg/m^3
