Approximately how many stone blocks make up the Great Pyramid?

Approximately 2.3 million stone blocks make up the Great Pyramid of Giza.

The estimate refers to the pyramid’s total masonry core, built for Pharaoh Khufu during Egypt’s Fourth Dynasty, around 2600 BC. Most blocks are local limestone quarried on or near the Giza Plateau. They vary considerably in size, with ordinary core blocks much smaller than the enormous granite stones used in the King’s Chamber and its surrounding structures.

The pyramid once had a smooth outer casing of bright white Tura limestone. Much of that casing was removed over the centuries, leaving the stepped appearance of the underlying core that visitors see today. Granite was transported from Aswan, hundreds of kilometres to the south, while limestone deliveries from Tura are documented in the ancient Diary of Merer.

The figure is an estimate, not an exact surviving inventory. That is why quiz questions properly use “approximately.” The often-repeated number of 2.3 million describes blocks, while estimates of the pyramid’s total mass are commonly expressed in millions of tonnes.
