**[SOLVED] Calaculate Mass of Cube submerged in oil and water**

## Homework Statement

A cube is submerged in water and oil the oil is on top, and forms a layer 10cm thick. the water is underneath and forms another layer 10cm thick. the cube has sides of 10.2cm, and has 2.3cm below the oil water line. the density of the oil is 790kg. I have worked out already the force on the top of the cube is 163 Pa, and on the bottom 1000 Pa. How do you work out the mass of the cube?

## Homework Equations

Pressure = Force/Area

Archimedes: The upward force is equal to the weight of fluid displaced by the block (?)

## The Attempt at a Solution
