 Homework Statement:

Please see the diagram below
A cube with side a = 0.1 m is immersed in 2 liquids as shown (upper liquid is oil and lower liquid is water). The value of h is 0.02 m and the value of d is 0.2 m
Find the hydrostatic pressure at the bottom of the cube
 Relevant Equations:
 Hydrostatic pressure = ρ . g . h
I am not sure about value of depth I need to use. What I did:
Hydrostatic pressure at bottom of cube = hydrostatic pressure by oil + hydrostatic pressure by water
= ρ_{oil} . g . d + ρ_{water} . g . h
Is it correct I use value d = 0.2 m for depth of oil and value of h = 0.02 m for depth of water to calculate the pressure?
Thanks
