Also known as the law of buoyancy.

Archimedes’ principle is the physical law of buoyancy, in that a floating body displaces a weight of fluid (gas or liquid) equal to its own weight. More specifically:

$$$weight\; of\;displaced\;fluid=weight\;of\;object\;in\;vacuum-weight\;of\;object\;in\;fluid$$$

Or,

$$$F_{bouyancy}=\rho \cdot g\cdot V$$$

where ρ denotes fluid density, V is volume of displaced fluid, and g is acceleration due to gravity.
