What is Hydrostatic Pressure and Pascal's Law of Pressure in a Static Fluid

Through some straightforward equations the article introduces and proves Pascal’s law and the preceding topic regarding “what is hydrostatic pressure.” The expressions involving Pascal’s derivations are explicitly discussed and illustrated through an example involving static fluid enclosed in a tetrahedron, whereas the definition of hydrostatic law is analyzed with an example of an elementary fluid content inside a prism shape under a certain depth from the open surface of the fluid.
