A cubical block of wood 0.100 m on a side and with a density 550 kg/m^3 of floats in a jar of water. Oil with a density of 750 kg/m^3 is poured on the water until the top of the oil layer is 0.035 m below the top of the block.
1. How deep is the oil layer?

Please tell me the idea on how to do this

  1. figure out how deep the block sinks into the water (so its displacement of water has the same weight as the block)

    Then subtract .035m from the height of the block above the water.
