Buoyant force of air mattress

  1. Apr 13, 2008 #1
    1. The problem statement, all variables and given/known data

    A 2.8 kg rectangular air mattress is 2.00 m long, 0.500 m wide, and 0.100 m thick. What mass can it support in water before sinking?

    2. Relevant equations

    Density = Mass / Volume
    Magnitude of buoyant force = Weight of fluid displaced
    Buoyant force = weight of floating object
    Weight of object x Buoyant force = Density of object / Density of fluid
    Density of water = 1000 kg/m3

    3. The attempt at a solution

    I can't figure out what I would need to do in order to answer the question or what I would need to find.
