The perpendicular height of the ascending and descending passages is 2 cubits and 2 palms and the width is 2 palms. The height of the queen's chamber passage is also 2 cubits and 2 palms and the width is also 2 palms. The perimeters of these passages is 8 cubits and four palms. The perimeter minus the height of the passage is 6 cubits and 2 palms. Since 2 palms is 2/7 of a cubit, the perimeter of the passage minus the height of the passage is 6 2/7 cubits, or 2pi. The perimeter minus the height, divided by the width, is pi.

Extended downward, the king's chamber shafts intersect 77 cubits above ground level and 22 cubits south of the midline of the pyramid. Since the horizontal sections of the king's chamber shafts are 84 cubits above ground level, this produces a rectangle with side lengths of 22/7:



The half base of the pyramid (220 cubits), plus the 22 cubits south of the midline for the intersection of the kc shafts is 242 cubits. The 242 cubit length over the 77 cubit length of the intersection point above ground level also produces a 22/7 rectangle:



Concerning the location of the entrance to the pyramid:
