How is the surface area of an average person is 2m^2 in the chapter pressure

We have to show surface area ,with few conditions that is by considering Force and Pressure to be respectively.

Explanation:

The atmospheric pressure is on Earth's surface.

The magnitude of the force exerted on a person by the atmosphere is .

Now to calculate surface area we can find it from and re-arranging it to.

So plugging the values,

Surface area

Hence from the above calculations we can say that surface area is .

So the surface area of an average person can be said to have , using the concept of pressure and force.

The total atmospheric pressure experienced by the person's whole body is, P = 202650 N/m²

Explanation:

Given data,

The surface area of the person, A = 2 m²

The standard atmospheric pressure is  P = 101325 N/m² (or), Pascal

This is the amount of pressure experienced by 1 m² body at sea level.

If the surface area of the person is, A = 2 m², then the pressure becomes,

                                  P = 2 x 101325 N/m²

                                    = 202650 N/m²

Hence the total atmospheric pressure experienced by the person's whole body is, P = 202650 N/m²
