It was built out of 186 stones. The average weight of each stone was almost 1,500 lb (680 kg) (.75 tons). They found that four or five men could use levers to flip stones less than a ton and roll them to transport them. 44 men took 22 days to complete the pyramid, including the carving of the stones.
Four or five men were able to use levers on stones less than one ton to flip them over and transport them by rolling, but larger stones had to be towed. Lehner and Hopkins found that by putting the stones on wooden sledges and sliding the sledges on wooden tracks, they were able to tow a two-ton stone with 12 to 20 men.

A badly damaged white Tura limestone pyramidion, thought to have been made for the Red Pyramid of Sneferu at Dahshur, has been reconstructed and is on open-air display beside that pyramid; it presents a minor mystery, however, as its angle of inclination is steeper than that of the edifice it was apparently ...
