Also, I love the Bible quizzes, please keep adding them, QM.
If you go by the great egyptian cubit for instance, which was about 53cm 4 cubits would be 212cm which would be very tall for these days and even moreso centuries ago.
If you go by the small greek unit, which was 34cm, 6 cubits would be 204cm.
Ow I forgot the spans, well that differs too, also not always measured the same way. And sometimes confused with palm.
