Explain Displaced If a object is held down in a container that is only a little larger than itself and the container filled with fluid then the volume of fluid displaced by the object can be alomst nothing yet the buoyancy force is unchanged as the upwards pressure depends only on the height and density of fluid Is it worth being explicit in the article to say the submerged volume even though the displaced volume can be less This is a somewhat similar problem to the bottle on the bottom the pool discussion
