RARE PROOF THAT THE PYRAMIDS WERE BUILT ON HUMAN CAN CARRY 100KG, AT A BARE MINIMUM, I'D SAY 1000 PEOPLE FOR THAT FIRST BLOCK

 RARE PROOF THAT THE PYRAMIDS WERE BUILT ON HUMAN CAN CARRY 100KG, AT A BARE MINIMUM, I'D SAY 1000 PEOPLE FOR THAT FIRST BLOCK

Spitballing the closest stone, it looks like 2x3x6m minimum. Say stone has a density of 3-4tons per cubic metre, we've easily got 100 tons.

For convenience, we'll assume a human can carry 100kg, so, at a bare minimum, I'd say 1000 people for that first block of stone
There appear to be 3 rows of 6 carrying the first stone. That's 18 people, so each is carrying about 5600kg or 12000 lbs in this photo.

To fit 1000 people under that first block of stone, if we assume 3x6m width and length, each person would need to occupy 0.018 m^2 (0.19 ft^2), or a square about 13cm (5 in) per side.

Google says that average American male has a shoulder width of 16in (41cm). Given that these men carrying the stone are likely to be very strong, and American men are generally overweight, let's say 16in/41cm should be about right.

Realistically, these workers should be able to function with training in a space about 2ft x 2ft (sorry for my American brain), or 60cm x 60cm.

That implies each one takes up 0.36m^2, so the maximum surface density of the stone over their heads must be ~300kg/m^2.

Given a stone density of 3 metric tons per m^3, we can say that the maximum thickness of the stone to be carried in this way must be 10cm, or about 4 inches.
