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.
Right. Ok, then. Go out into your back yard and mark out 30 cubits on the ground with your arm and then come back and tell me that when you are done your measurement is exactly 30 times the distance between the tip of your elbow and the tip of your finger.
I suggest that the variant will be much greater than 29.89/30.00.
You're a "scientist". Go do the experiment and tell me if I'm wrong.

Since you are afraid to give straight answers to my questions, I suppose there's no point in posting to you anymore anyway.
18" cubits, 27" cubits yards, meters or inches - none would matter for PI is a RATIO!!!
