As I stated before a cubit is an approximation and not an exact measurement, therefore your previous answer was incorrect. So what is the number of cubits? Hint: You have to round it off.
No. A cubit varied depending on the person doing the measuring, because it was a body dimension; but if they same person measured two lengths in cubits, the ratio of the two measurements would not contain any error due to that variability. We call this phenomenon covariance.
So it is your who are incorrect, and you're still being a jackass. And all to try to argue tendentiously that the Hebrews did not think pi was 3, something that is attested in the Talmud as well as Kings and Chronicles.
Go away, and troll no more.
