As you know I have been on about these numbers for many years especially in regards to the pyramids and a unit of measure found in the Indus Valley and in Britain which is known as an Indus Valley foor or Saxon foot 13.2 inches.
The architects of the pyramids, I believe, incorporated these numbers into their design. I believe it was central to the overall plan because it enabled these wonderful buildings to be read. I dont imagine the architects would have ever thought a system so perfect would simply have been altered to such a degree. But time did it and we end up with 16.5 feet in a rod instead or 15 and 660 feet in a furlong instead of 600 and 43560 square feet in a mile instead the perfect 36000.
For instance consider the number 216 [www.google.com.au]
If these numbers meant so much to ancient scientists and architects then naturally they would incorporate them into the design of their buildings. I believe that there is a much deeper meaning here because these numbers describe the then known universe. Their observations led to the discovery of the precession of the equinoxes 25920 years and 1/12 th of that being 2160, part of the Zodiac.
And that is what happened at Giza they incorporated these numbers into the buildings because these numbers 540 72 etc 216 432 1296 2592 and that is part of what Giza is all about.
