Not only was the Great Pyramid of Giza designed using the royal cubit unit of measure (20.63 modern inches), so too, over a thousand years later, was the Temple of Solomon (a cubit slightly longer at 20.67 modern inches), and not by coincidence, the Hunab unit of measure of ancient Mexico exactly twice the length of the royal cubit, because timekeeping was the means by which geometry (earth measure) for precise longitude was achieved, hinted in the base 6 sexagesimal number system of the Sumerians of Mesopotamia, and in the base 6 Hindu yugas of time (see Page titled Great Pyramid for Navigation).
