the air pressure acting on the roof of your house comes from the air within a few feet of your rooftop
[sqrt(18000 ft2) * (1 m / 3.28084 ft)]2 = 1672.25 m2
It depends on what gas, at what pressure, etc.
18000 what? sq miles? Then the answer is, strangely enough, exactly 18000.
air
The atmoshperic pressure at 18,000 feet above sea level is 280 mm Hg.
Air at 18000 ft is much less dense therefore making it harder for the hujman body to intake oxygen and filter it through the lungs.
18000 square feet are 0.4132231 acres.
There are 0.3048 metres in one foot. Therefore, 18000 feet is equal to 18000 x 0.3048 = 5486.4 metres.
18,000 feet = 3.41 miles.
18,000 feet = 5.4864 kilometers
18,000 feet = 3.41 miles.
1 mile = 5280 ft so 18000 ft = 3.409091 miles.

if a meter is 3 feet, its 1,500 feet or 18000 inches or 36,000 centimeters
