# what is the weight of the air within a room having dim.of 10ft long x 12 ft wide with 10ft 6in ceilings?

Relevance

At STP the weight of the air is 101.68 lbs.

We assume that the room is at standard pressure and temperature (STP).

STP corresponds to 273 K (0° Celsius) and 1 atm pressure.

Since 1 cubic foot of air at standard temperature and pressure --- assuming average composition weighs approximately 0.0807 lbs. So roughly 13 cu ft of air at STP will weigh 1 pound.

If we take your given dimensions and calculate the room volume:

(10') x (12') x (10.5') = 1260 cu ft room volume

weight of air calculation:

(1260 cu ft) x ( 0.0807 lbs/ cu ft) = 101.68 lbs at 273 K (0° Celsius) and 1 atm pressure.

Weight of air in the room is 101.68 lbs

i'm continually having an identical venture, I nevertheless degree each and every thing in feet and inches, then ought to parent it out in metric for the save assistants. I many times calculate approximately 40 inches to a metre and artwork from there i'm not at all too a ways out the two, good success.

For a first approximation,at average room conditions, about 13 cubic feet of air weighs a pound
