It's been a little while since I took chem, but I can say with confidence that you may need more information than what was provided.
Is it really 5.5 m SQUARED, and not cubed?
Either way, I feel as though you need the number of moles of gas present (or the mass of the gas), and the temperature of the air, as they do affect this sort of thing.
PV=nRT
...
Except that there is not V. You have area.

Is the amount of substance in a certain volume the pressure?
No, the pressure is the force exerted by the substance on the walls of its container. The word that comes to mind for "amount of substance in a certain volume" is concentration, though it might also be a somewhat awkward way of describing density.The amount of substance in a certain volume is the density of the substance. Pressure means the force applied in a unit area. So the amount of substance in a certain volume is not the pressure.
Why does liquid exert pressure on the walls of the container?
The gas molecules are moving at speeds of hundreds of metres per second. When they strike the vessel, they are accelerated in the opposite direction. The pressure on the vessel is the force exerted to cause that acceleration.
Why does the pressure exerted by a gas at constant temperature decrease when the volume of the gas is increased?
Greater pressure on a gas will compact the gas into a smaller volume. If the compressed gas is then warmed, it will try to expand, and the pressure the gas exerts on the container will increase. If the pressure becomes greater than the container can hold, the container will explode or split and the excess gas pressure released.
What is the different between turgor pressure and diffusion?
The difference of turgor pressure and diffusion is that turgor pressure is an osmotic pressure exerted by the contents of a plant cell against its cell wall; while diffusion is a movement of molecules from an area higher concentration to an area lower concentration.
List different SI units of pressure?
Pressure is a measure of force per area. The SI unit of pressure is a Pascal (Pa) which is equivalent to a Newton per meter squared (N/m2).
What is the pressure exerted by a piston if a force of 12N is applied over an area of 1.2m squared?
Pressure is force / area. Just divide the force by the area. The answer is in pascal.
The force exerted on a surface divided by the area over which the force is exerted?
Pressure is the force exerted on an object divided by the area where the pressure was applied.
What is the force exerted on surface divided by the area over whech the force is exerted?
That's the pressure on that particular area.
How do you call the force exerted on a surface divided by the area over which the force is exerted?
Pressure
What force is exerted on an object in with an area 2.5 M squared if the pressure is 99500 PA?
99500 x 2.5 = 248,750 Newtons
What is the scientific definition of force?
Pressure depends on the quantity of force exerted and the area over which the force is exerted
What is the pressure exerted by a fluid is the total force exerted by the fluid divide by?
area
Pressure is calculated by dividing force by WHAT over which the force is exerted?
area
What happens to pressure of the force exerted on a given area increases?
The pressure exerted outward by fluids in your body balances the pressure exerted by the atmosphere on the surface of your body. the pressure increases
What is the force on a surface divided by the area of that surface?
The force that is exerted on a surface divided by the area of the area is pressure. The standard unit of pressure is the Pascal.
Pressure is equal to the amount of force exerted on an object divided by the volume over which the force is exerted?
Over the area not volume
Why pressure is inversely proportional to volume?
Pressure is given as Force per unit area (ie. 1 Pascal of pressure is the experienced when 1 Newton of force is exerted over an area of 1m^2). Therefore Pressure and Force are proportional to one another. Area the force is exerted over is inversely proportional to pressure.
