Which is the smallest of the three main Pyramids of Giza?

The Pyramid of Menkaure is the smallest of the three main Pyramids of Giza, located on the Giza Plateau in the southwestern outskirts of Cairo, Egypt. It is thought to have been built to serve as the tomb of the fourth dynasty Egyptian Pharaoh Menkaure.

Menkaure's pyramid had an original height of 65.5 meters (215 feet).

In the mortuary temple the foundations and the inner core were made of limestone. The floors were begun with granite and granite facings were added to some of the walls. The foundations of the valley temple were made of stone. However both temples were finished with crude bricks. Reisner estimated that some of the blocks of local stone in the walls of the mortuary temple weighed as much as 220 tons, while the heaviest granite ashlars imported from Aswan weighed more than 30 tons.

It was not unusual for a son or successor to complete a temple when a Pharaoh died, so it is not unreasonable to assume that Shepseskaf finished the temples with crude brick. There was an inscription in the mortuary temple that said he "made it (the temple) as his monument for his father, the king of upper and lower Egypt." During excavations of the temples Reisner found a large number of statues mostly of Menkaure alone and as a member of a group. These were all carved in the naturalistic style of the old kingdom with a high degree of detail evident.
