In a confined liquid, pressure:

Pressure in a confined liquid is transmitted equally in all directions, so at a given pressure the force it exerts on a surface is proportional to the surface’s area (F = P × A). Therefore, if two surfaces have equal area and are at the same pressure, the liquid applies equal forces on them. This direct relationship between pressure and contact area is the essence of how a confined liquid pushes on surfaces. (Note that pressure does increase with depth in a static liquid, but the statement about equal forces on equal areas captures the fundamental isotropic nature of pressure.)
