Of course I meant Euler. Pascal used primes in a different manner in Pascal Triangle and other work.
In RMP 38 Ahmes converted 10 hekat to 3200 ro units. A ro was 1/320 of a hekat. A corrected 22/7 round cylinder volume would have been closer to 318.214 ro, documenting that the 320 ro standard calculation contained a volume over statement error of 1.786 ro.
Note that a modern definition of pi would have found an additional 0.00127 ro error. Hence, Ahmes' implied use of pi = 22/7 was over 99% correct.
