There would be no justification for proposing anything other than round numbers of whole cubits for the antechamber of the Red Pyramid except for at least five facts:

Firstly, it is an astonishing geometric model for a precise conversion.

Secondly, the ancient Egyptians were good at building precisely.

Thirdly, the relationship between palms and cubits is the simplest way to conceive a scale model for the cubit of 7 palms.

Fourthly, the long grooves on the third over-laps of the Grand Gallery of the Great Pyramid run the entire length of the gallery where the separation is 22/7 cubits or 22 palms, and each of 7 pairs of over-laps reduce the width between the side walls by 2 palms from 4 cubits (28 palms) at the widest point to 2 cubits (14 palms) at the ceiling, so we have clear evidence that the cubit was divided into 7 palms in the Fourth Dynasty.

Fifthly, the King's Chamber of the Great Pyramid is an elegant scale model of the size and shape of the Great Pyramid on a scale of one digit to one cubit with the palm divided into 4 digits, and the scale model is based on the ratio of the circumference (22) to the diameter (7) of a circle for the very precise ratio 22/7.

Many more facts are apparent from the main burial chamber of Khafre's Pyramid which reflects not only the size and shape of the pyramid, but also the design of his father's Great Pyramid and his grandfather's Red Pyramid.

This was the reason why I posted recently, but I appreciate that Khafre's Pyramid has never attracted much geometric interest even though the slope of the faces conforms to a model of a 3 : 4 : 5 right-angled triangle.
