Is this not a single assumption based upon a measured height? Please do not make the assumption that I posted without giving the problem a second thought.

First assumption.

Second assumption using the value of 22/7 rather than Pi.

Third assumption using out-of-date data.(See Cole's data, not Petrie's)

I was being kind to you before. Please explain how the roof of the ante chamber also fits into your calculation of margin of error.
