While pyramids are associated with Egypt, the nation of Sudan has 220 extant pyramids, the most numerous in the world.
Most pyramids had a polished, highly reflective white limestone surface, to give them a shining appearance when viewed from a distance.
The capstone was usually made of hard stone – granite or basalt – and could be plated with gold, silver, or electrum and would also be highly reflective.
A pyramid's design, with the majority of the weight closer to the ground, and with the pyramidion on top means that less material higher up on the pyramid will be pushing down from above.
This distribution of weight allowed early civilizations to create stable monumental structures.
As such, a pyramid has at least three outer triangular surfaces (at least four faces including the base).
