Buoyancy Problem

  1. Jan 9, 2012 #1
    1. The problem statement, all variables and given/known data
    A pig of mass (1158kg) is placed on a fart made of dry wood. The raft completely submerged in water so that the raft's top surface was just level with the surface of the lake. If the raft's volume was 3.40 m^3, what was the mass of the raft's dry wood? Density of water is 1000 kg/m^3

    2. Relevant equations
    m' = (p2 - p1)V
    p = density
    V = Volume

    Buoyant Force
    B = pfluid(g)Vobj

    3. The attempt at a solution
    I have no idea where to begin with this. The only density I am given is of water not of the wood.

    Buoyant force = weight of pig and raft
