How much deeper does the barge lower?

  1. Jan 25, 2015 #1
    1. The problem statement, all variables and given/known data
    1. A rectangular barge floats in freshwater. When a 400 kg block is loaded on the 5 m long by 2 m wide barge, the barge sinks a few centimeters deeper. How much deeper does the barge lower?
    2. Relevant equations
    Archimedes' principle
    This is where I am stuck. My text book doesn't talk much about this at all. barge.jpg

    3. The attempt at a solution

    You've done all the hard work. How much deeper does the barge have to "sink" to displace the extra 0.4 m3?

    Yes, but you could have got there a bit faster from knowing the volume displaced and the area.
