Homework Help: Determining density of a block

  1. Sep 5, 2008 #1
    1. The problem statement, all variables and given/known data

    if I have a block of unknown density and if it is 35% submerged in a liquid of density 2.5g/cm^3
    what is the density of the block


    2. Relevant equations
    d=m/v


    3. The attempt at a solution
    I thought that if the block was 100% submerged just under the surface, its density would equal that of the liquid.
    Since it is 35% submerged, i thought i would approach it this way.
    2.5/100=x/35
    87.5=100x
    x=0.875g/cm^3
    Is that correct?
