Webpages Related to the Tag Pyramid

A pyramid is a structure whose outer surfaces are triangular and converge to a single step at the top, making the shape roughly a pyramid in the geometric sense. The base of a pyramid can be trilateral, quadrilateral, or of any polygon shape. A pyramid is also a three-dimensional figure that has a flat polygon base. All the other faces are triangles and are called lateral faces. The number of lateral faces equals the number of sides on its base. The largest pyramid in the world is the Great Pyramid of Cholula in Mexico. It is also known as Tlachihualtepetl (Nahuatl for artificial mountain). It measures 400 by 400 meters (1,300 by 1,300 feet) and has a height of 55 meters (180 feet). The largest pyramid in Egypt is the Pyramid of Khufu (also known as the Great Pyramid of Giza). It is the only one of the Seven Wonders of the Ancient World still in existence, despite its being the oldest wonder by about 2,000 years.
