    What is the relationship between the amount of water and
    object displaces and the weight of the object?

    Ancient Greek, Archimedes of Syracuse, first discovered the law of buoyancy aka Archimedes's principle: the buoyant force is equal to the weight of the displaced fluid. The buoyant force is equal to the weight of the displaced fluid. If the weight of an object is less than the weight of the fluid it would displace, if it was fully submerged, then the object is less dense than the fluid and it floats at a level so it displaces the same weight of fluid as the weight of the object.
