Can anyone explain me the Archimedes principle

Hey there !
Archimedes' principle states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces and acts in the upward direction at the center of mass of the displaced fluid.
If the weight of an object is less than that of the displaced fluid, the object rises, as in the case of a block of wood that is released beneath the surface of water or a helium-filled balloon that is let loose in air. An object heavier than the amount of the fluid it displaces, though it sinks when released, has an apparent weight loss equal to the weight of the fluid displaced. In fact, in some accurate weighings, a correction must be made in order to compensate for the buoyancy effect of the surrounding air.
Hope it helps you !

1️⃣Archimedes principle states that when a body is immersed wholly or partially in a liquid, it experiences an upward buoyant force of magnitude equal to the weight of the liquid displaced by it.
-------------------------------------------------------
Buoyant force = Weight of displaced liquid
Weight of displaced liquid = Mass of the displaced liquid × Acceleration due to gravity
= Density of the liquid × Volume of the displaced liquid × Acceleration due to gravity
-------------------------------------------------------
1️⃣∴Volume of the displaced liquid = Volume of the object that is immersed in the liquid
2️⃣∴Weight of the displaced liquid = Volume of the object immersed in the liquid × Density of the liquid × Acceleration due to gravity
------------------------------------------------------
Hence, we can write the magnitude of the upthrust on an object that is immersed in a liquid as:
Buoyant force = Volume of the object × Density of the liquid × Acceleration due to gravity Since buoyant force depends on the density of the liquid in which it is immersed, it is different in different liquids for the same object.
