How many stone blocks make up the Great Pyramid of Giza, per the standard Egyptological estimate?

Answer

2,300,000 blocks

At an average of about 2.5 tonnes per block, the pyramid weighs nearly 6 million tonnes — more than 500 times the weight of the Eiffel Tower. Built in roughly 20 years, that averages out to a block set every few minutes, day and night.
