So why do fluids exert an upward buoyant force on submerged objects. The buoyant force is equal to the weight of that volume of water. When a body is immersed fully or partially in a fluid, it experiences an upward force that is equal to the weight of the fluid displaced by it. If the body was smooth and rounded like the hull of a ship it.
So the way to think about is that once you put the object in the water it could be a cube, or it could be anything.
