<P> An object that sinks displaces an amount of fluid equal to the object 's volume . Thus buoyancy is expressed through Archimedes ' principle , which states that the weight of the object is reduced by its volume multiplied by the density of the fluid . If the weight of the object is less than this displaced quantity , the object floats ; if more , it sinks . The amount of fluid displaced is directly related ( via Archimedes ' Principle ) to its volume . </P>
