Quite possible indeed, I was just being contentious for the fun of it. Honestly, I personally think the "pi" explanation the more likely. The professional Egyptologists claim it is impossible because the Egyptians didn't know pi that accurately. But they base that on papyri that are 1000 years more recent than the date of the pyramid, in which pi was approximated by 19/6 - about = the sq. root of 10. But that disregards the possibility that the level of Egyptian technical expertise deteriorated in the intervening 1000 years. In fact the building skills seemed to have peaked around the time of building Cheops' pyramid and deteriorated subsequently.
One interesting source, if you aren't already familiar, is "Fingerprints of the Gods" by Graham Hancock. Many would dismiss it as crackpot, although Hancock is a "mainstream" journalist. Even if some of the speculation is a little far- out, the book is still a good source of a lot of interesting information. I find it amusing that the Encyclopædia Britannica gives the dimensions of the pyramid but never mentions the fact that pi appears as it does. This presumably because the "experts" have dismissed the fact as mere coincidence and not possibly being of any significance.
