Why do pyramids have a slanting face?

Pyramids have slanting faces primarily for structural stability and aesthetic reasons. The slanted design helps distribute weight evenly down the sides, allowing the massive stone blocks to support each other and resist collapse. Additionally, the angular shape symbolizes the rays of the sun, which was significant in ancient Egyptian culture, representing the connection between the pharaohs and the divine. This shape also facilitated the construction process, enabling workers to build upwards more efficiently.
