Water is denser than air so the pressure is much greater underwater than it is in the air. Ascending 20 meters (50ish feet)underwater is about the same amount of pressure as like 1000 feet in the air

Dear friend you have not specified which in year you are targeting your admission .
At about 30,000 feet, the air is thinner and the aircraft has little resistance at that height, because of that little resistance the plane can fly much further
The dielectric breakdown of air at 40,000 feet (approximately 12,200 meters) is lower than that at sea level due to decreased air pressure. At sea level, the breakdown voltage of air is about 3 million volts per meter (MV/m), but at higher altitudes, the reduced air density results in a breakdown voltage of around 1 to 2 MV/m. This means that electrical discharges can occur more easily at high altitudes, affecting aircraft and other high-altitude operations.

50,000 feet
Yes. An air mile is 6,076.115 feet. A 'land' mile is 5,280 feet.
288 cubic feet of "air" or 19 cubic feet of pure oxygen .
a caribou can jump 6 feet in the air if it wants to if it is in trouble it will jump 10 feet in the air
Air cannot be measured in square feet, please re-define this for a proper answer.
