Airplanes typically fly at altitudes of 6 or 7 miles. Estimate the air pressure and density outside the plane at this altitude. The air pressure you calculated above would be far too low for humans to hang out in, so airplane cabins are pressurized to reduce (though not eliminate) this drop in pressure and density. "Cabin altitude" refers to the equivalent elevation that the airplane cabin is maintained at to make sure everyone can breathe as comfortably as possible, and is typically around 8000 feet. Based on this, calculate air pressure and density inside a plane pressurized to this "cabin altitude". Compare the air pressure you calculated in part A to the one you calculated in part B, and use it to explain why oxygen masks might be necessary if the airplane is damaged midflight and loses pressure.
