<P> Based on these estimates , building the pyramid in 20 years would involve installing approximately 800 tonnes of stone every day . Additionally , since it consists of an estimated 2.3 million blocks , completing the building in 20 years would involve moving an average of more than 12 of the blocks into place each hour , day and night . The first precision measurements of the pyramid were made by Egyptologist Sir Flinders Petrie in 1880 -- 82 and published as The Pyramids and Temples of Gizeh . Almost all reports are based on his measurements . Many of the casing stones and inner chamber blocks of the Great Pyramid fit together with extremely high precision . Based on measurements taken on the northeastern casing stones , the mean opening of the joints is only 0.5 millimetre wide ( 1 / 50 of an inch ) . </P>
