The Royal Cubit comprised 7 palms, or hands, and 28 fingers. The video argues that the Great Pyramid’s proportions connect to 22/7 ≈ π: it stood about 280 Royal Cubits high with a base of 440 cubits per side, so 440 ÷ 140 = 22/7. This numerical fit does not establish that the builders deliberately encoded π. The Royal Cubit was a pre-existing standard used at Giza, not created for the pyramids, and its use cannot establish that an artifact postdates them. 🏛️⏳

Key facts

The Royal Cubit contained 7 palms, or hands, each 4 fingers long, for 28 fingers; the common cubit had 6 palms.
22/7 approximates π; it is not exactly equal to π.
The Great Pyramid was about 280 Royal Cubits high and 440 per side, giving a perimeter of about 1,760 cubits. The figures become 7 and 44 only when grouped in 40-cubit modules; 440 ÷ 140 = 22/7.
The Royal Cubit was used before Giza and was not created specifically for the pyramids.
Use of the Royal Cubit does not require an artifact to postdate the pyramids; the unit was used in both earlier and later periods.
