A pyramid is a construction whose external surfaces are three-sided and meet to a solitary advance at the top, making the shape about a pyramid in the mathematical sense. The foundation of a pyramid can be three-dimensional, quadrilateral, or of any polygon shape. Accordingly, a pyramid has at any rate three external three-sided surfaces (at any rate four appearances including the base). The square pyramid, with a square base and four three-sided external surfaces, is a typical variant.

A pyramid's plan, with most of the weight nearer to the ground, and with the pyramidion at the summit, implies that less material higher up on the pyramid will push down from a higher place. This appropriation of weight permitted early civic establishments to make stable amazing designs.

Human advancements in numerous pieces of the world have assembled pyramids. The biggest pyramid by volume is the Great Pyramid of Cholula, in the Mexican territory of Puebla. For millennia, the biggest designs on Earth were pyramids—first the Red Pyramid in the Dashur Necropolis and afterward the Great Pyramid of Khufu, both in Egypt—the last is the just one of the Seven Wonders of the Ancient World actually remaining.
