A pyramid is any three-dimensional polyhedron where the faces other than the base are triangular and converge on one point, called the apex.
The base of a pyramid can be any polygon but is typically a square, leading to four non-base faces. – from Wikipedia.
The most famous pyramids are the ones found in Egypt.
There are three pyramids in Giza – there is the Khufu’s Pyramid, Khafre’s Pyramid and Menkaure Pyramid.
Khufu’s Pyramid, is the oldest and largest of the three pyramids bordering what is now Cairo, Egypt and is the only remaining member of the Seven Wonders of the Ancient World. It is believed the pyramid was built as a tomb for Egyptian pharaoh Khufu. The Great Pyramid was the tallest man made structure in the world for over 3,800 years. – from Wikipedia

Menkaure’s Pyramid, is the smallest among the three pyramids and the tomb of Egyptian Pharaoh Menkaure. It was probably completed that time between the 26th century BC.
I wasn’t expecting to be THERE – for real – but there I am standing right in front on one of the Ancient Seven Wonders of the World and the only surviving structure in modern times. Woot.
