Khufu’s Pyramid at Giza was a massive undertaking, requiring approximately two million stone blocks weighing an average of 2.5 tons to be set into place, five every minute during the first years of construction [1]

mfs didn’t even use wheels; they were just sliding those huge blocks up ramps! It is pretty amazing.

Was no one really smart enough to put wheels on the blocks? I guess it was probably an axle strength issue.
