Help in fluids problem

  1. Nov 3, 2005 #1
    A 2cm thick bar of soap is floating on a water surface so that 1.5cm of the bar is underwater. Bath oil of specific gravity 0.60 is poured into the water and floats on top of the water. What is the depth of the oil layer when the top of the soap is just level with the uper surface of the oil?

    HINT: What is the density of the soap bar?

    P.S. Have you done ANY work at all on this problem?

    There is no density for soap bar. I did but without benefit.

    The hint was a suggestion that you should be able to use the information provided to determine the density of the soap bar. The problem wouldn't have been assigned if you hadn't already learned something about buoyancy.
