I think that you may have left out a zero.
I live at 3700 feet and breathe quite well.
If it was 30,000 then it would be hard to breathe because at Mount Everest the air is thin. Gravity holds the air next to the ground and it begins to be thin on top of that very high mountain. So, think of air as a liquid that rests on the earth. It is only so thick ad then there is none in space.
When the aircraft is on the ground it is about 3 metres. When it is in the air it can be up to 5 nautical miles and 3000 feet
There are 3 feet in one yard. Therefore, 3000 feet is equal to 3000/3 = 1000 yards.
9842.5 feet?
25% of 3,000 square feet= 25% * 3000= 0.25 * 3000= 750 square feet
3000 millimeters = 9.84 feet.
3000 feet = 0.9144 kilometers.
3000 kilometres = 9 842 519.69 feet
333.33 yards in 1,000 feet.
How much what? 3,000 feet = 0.568 miles 3,000 feet = 0.914 kilometres 3,000 feet = 914.4 metres
This Is Because the atmospheric pressure of earth is always acting.We did not feel this because our blood pressure is equal to atmospheric pressure.It is perfectly possible to breath at this altitude. Mt. Everest, which is much higher than this, has been climbed without any breathing aids.
3000 square meters = 32,291.7 square feet.
There are 283 separate mountains over 3000 feet in Scotland with a further 227 peaks on those mountains over 3000 feet.
