Some stones may have been roughly cut, but that really makes no difference. 2.3 million 5000 pound stones, cut, moved and placed over the course of a few decades. That's maybe the largest undertaking in human history and there were 3 of those with several minor pyramids and a hundred more pyramids scattered all over Egypt. Then you have the dimensions which are astonishing in itself. Each side lines up perfectly with North, South, East and West. There are quite a few of those crazy facts about the pyramids. Marvel of engineering 5000 years ago.
The size and weight of pyramid blocks varied depending on their location in the pyramid:
- Core stones
The average size of core stones was 1.27 m x 1.27 m x 0.69 m (50 in x 50 in x 27 in) and they weighed around 2,500 kg (5,511 lbs).
- Higher layers
Smaller blocks, around 1.0 m x 1.0 m x 0.5 m (approx 1.3 tons), were used in higher layers because they were easier to transport.
- King's Chamber
Stone blocks in the King's Chamber weighed between 50,000–60,000 kg (110,000–132,000 lbs).
- Above the King's Chamber
The largest granite stones in the pyramid, located above the King's Chamber, weighed between 25–80 tons each
