> "Petrie supposedly deduced a royal cubit of 20.63 inches to produce a base perimeter of 440 cubits and a height of 280 cubits"
If we use Petrie's "wrong" average of 20.632 we get 440 x 20.632 = 9078.08
However I believe the average base length is 9069 inches
If we assume 440 cubits for the base we get a cubit of 9069 / 440 = 20.611 so I really don't understand why Petrie picked that for his average for it is not what his own numbers show.
If we use 20.632 we get 439.56 cubits as the average.
Here is Petrie's data:
