SOCIAL SCIENCE
Around 5.5 million tonnes of limestone, 8,000 tonnes of granite (transported from Aswan, 800km away), and 500,000 tonnes of *mortar were used to build the Great Pyramid. This mighty stone formed part of an outer layer of fine white limestone that would have made the sides completely smooth.
*Mortar made from the mineral gypsum (calcium sulfate dihydrate). It was essentially a mixture of plaster and sand and was quite soft.
