Buoyancy/Barge problem

  1. Jan 25, 2009 #1
    1. The problem statement, all variables and given/known data
    A barge 150 ft. long and 30 ft. wide is to carry a payload of 10-ton light tanks over water. If the barge is to sink no more than an addictional 1 ft, how many tanks can be loaded?


    2. Relevant equations



    3. The attempt at a solution

    Buoyant Force = fluid density x volume submerged x gravity
    = (1 g/cm^3 x 1kg/1000g) x (4500 ft^3 x 28.317L/1ft^3 x 1000cm^3/1L) x 9.8 m/s^2
    = 1,248,779.7 N

    I've gotten this far and don't know what to do next. Also, this may be completely wrong.
