A perspective on just how immense the Great Pyramid of Giza truly is.
When it was built it was 146.5 metres (481 feet) tall. It was the tallest building in the world for over 3,800 years. Erosion and other causes have shrunk it to 138.8 m. The base is 230.34 metres (756 ft) in length and its volume is more than 2,500,000 cubic metres (88,000,000 cubic feet), while the weight is estimated at 5.9 million tonnes.
The Great Pyramid of Giza consists of an estimated 2.3 million blocks of Tura limestone (mostly), granite and other types of stone. The largest granite stone in the pyramid is located in the King’s chamber, weighs about 80 tonnes and was probably transported from Aswan, more than 800 km (500 mi) away.
