Let us start with the most basic problem: Is the transport of 6 Mio. tons up the pyramid possible with muscle power in less than some hundred years? I start with a simple calculation which is not a model for the stone transport but shows only the general (im?)possibility of muscle transport.

Let's say a worker can carry a "part" of the pyramid with a weight of about 40 kg. He puts this into a backpack of some kind and climbs up the pyramide with the help of ladders or so (the weight is no problem, I was once in Nepal, where Sherpas carried 50 kilos and more and were still running up the mountains...)

Now we can calculate the average height the worker has to reach. In a pyramid like Chufus 50% of the material is used up in about 30% of the pyramid height, so the worker has to climb to an average height of 50 meters.
Lets give him a minute for each meter, and additional 10 minutes to carry the portion of pyramid on the working level to its intended position, and half an hour for climbing down and for a small rest. The worker can carry 265 kg in 10 hours of work this way. With this easy work speed our master worker would need 23 Mio. days to carry the whole 6 Mio. tons, thats about 62000 years.

On the other hand: 62000 workers would need only one year (!) to do the whole job. 5-10000 workers would have had no problems in carrying the material during the needed time frame.

Stone cradle Of course we could expand this "portion of stone" carry-model into a working model. We could put a 2.5 t stone on a heavy transport framework built from massive wooden beams. About 50-60 persons would be necessary to carry such a construction as shown in the beside picture. With 8 workers at each beam on the front and behind, and 7 on each of the sideway beams a block could have been transported. The smaller blocks near the top would need even less transporters. But of course this is only a model. The favoured way was the transport by ramps and sleds. This will be calculated on the next pages.
