Fluid statics, often known as hydrostatics, is a branch of fluid mechanics that investigates the state of balance of a floating and submerged body, as well as the pressure in a fluid, or imposed by a fluid, on an immersed body.

The force per unit perpendicular area across which the force is exerted is known as pressure. Pressure is defined as follows in equation form:

\(P = \frac{F}{A}\)

The pressure given is:\[{\rm{60 mm Hg}}\].

The surface area creating the pressure is \[{\rm{600 c}}{{\rm{m}}^{\rm{2}}}\].

The force is given by,

\(F = P \times A\)

By putting all the value into the equation, we get:

\[\begin{array}{c}F = P \times A\\F = h\rho g \times A\\ = \left( {0.06\;{\rm{m}}} \right)\left( {13600\;{\rm{kg/}}{{\rm{m}}^3}} \right)\left( {9.8\;{\rm{m/}}{{\rm{s}}^2}} \right) \times 0.006\;{{\rm{m}}^2}\\ = 480\,\;{\rm{N}}\end{array}\]

Therefore, force acting into the surface per area is: \[{\rm{480 N}}\].
