Given:

L=length,

W =width,

H = height,

R = radius,

m = mass,

g = acceleration due to gravity.

To find:

The correct formula for the pressure among the given choice.

Step-by-step explanation:

The pressure is defined as the force per unit area. Thus the pressure is given by the ratio of the force applied to the area for which the force is applied.

Thus,


P=(F)/(A)

Where F is the force applied and A is the area.

The weight is a force and is given by the product of the mass of the object and the acceleration due to gravity.

That is weight is given by,


F=mg

The area is given by the product of the length and the width.

Thus the area is given by,


A=L* W

Thus the pressure is given by,


P=(mg)/(L* W)

Final answer: Thus the correct answer is option C,


P=(mg)/((L* W))
