The volume for any pyramid = 1/3*base area*perpendicular height
What does the term square pyramid mean?
A square pyramid is a pyramid with a square base. It has 4 outer faces, all of which are triangles, that meet at the same point perpendicular to the centre of the base. All pyramids have at least 4 faces (including the base), where the outer faces are all triangular while the base can be trilateral, quadrilateral, or any other polygon. The quadrilateral form (the square pyramid) is the most common form of pyramid, and is the form associated with the Egyptian pyramids.
What are the properties of square based pyramid?
1. Base is a square 2. The apex is usually directly above the centre of the square (ie if you drop a perpendicular from the base of the square passing through the apex, it hits the square in the middle)
What kind of pyramid has five sides?
None. A pyramid is defined as a structure with a square base and lines from the corners of that square coming together at a single point above or below the base level. If it has 5 sides, it's no longer a pyramid.
