Wikipedia: Archimedes’ principle
Archimedes’ principle (also spelled Archimedes’s principle) states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially, is equal to the weight of the fluid that the body displaces. Archimedes’ principle is a law of physics fundamental to fluid mechanics. It was formulated by Archimedes of Syracuse.
