Answer:
Force, [tex]F=2.02\times 10^6\ N[/tex]
Explanation:
It is given that,
Length of the room, l = 4 m
breadth of the room, b = 5 m
Height of the room, h = 3 m
Atmospheric pressure, [tex]P=1\ atm=101325\ Pa[/tex]
We know that the force acting per unit area is called pressure exerted. Its formula is given by :
[tex]P=\dfrac{F}{A}[/tex]
[tex]F=P\times l\times b[/tex]
[tex]F=101325\times 4\times 5[/tex]
[tex]F=2.02\times 10^6\ N[/tex]
So, the total force on the floor due to the air above the surface is [tex]2.02\times 10^6\ N[/tex]. Hence, this is the required solution.
