The ancient Royal Cubit was divided into 7 palms and 28 fingers. This connects to Pi = 22/7 - a fraction using the sacred number 7. The Great Pyramid's original design used a base side length of approximately 440 Royal Cubits, which relates to Pi through the formula 440/140 ≈ π (where 140 is half the pyramid's height of 280 cubits). The Royal Cubit was a pre-existing standard adopted for construction at Giza, not created specifically for it. 🏛️⏳
