A pyramid is a generic term and can have any number (>3) of plane faces. A triangular pyramid has 4 faces, a rectangular one has 5, and so on. A pyramid whose base has n sides has n+1 faces.
How many what? If you mean sides of a square based pyramid 5
A pyramid is a generic term. There are pyramids with triangular bases, square or rectangular or quadrilateral bases, pentagonal base and so on. A pyramid whose base is a polygon with n sides has n+1 sides (which are the same thing as faces), and n+1 vertices.
rectangular pyramid, square-based pyramid, trapezoidal pyramid any pyramid whose base is a shape with only four sides
I presume the question is meant to be: How many sides does a pyramid have? The answer is 4 or more. A pyramid has a polygonal base where the polygon can have 3 or more sides. Corresponding to each of these sides there will be a triangle rising to the apex of the pyramid. In all, a pyramid whose base is a polygon with n sides will have n+1 faces (sides).
A nonagonal pyramid. A pyramid whose base is an n sided poygon will have n+1 faces in all.
pyramid An pyramid is a geometric solid of the shape made famous by the royal tombs of ancient Egypt. It is a solid whose base is a polygon and whose lateral faces are triangles with a common vertex
A pyramid is a generic term used to describe a polyhedron with a polygonal base and a number of triangles rising from that base to meet at an apex. A pyramid whose base is a polygon with n-sides (or vertices) has n+1 faces, n+1 vertices and 2n edges, where n >= 3. So a pryramid can have 4 or more faces.
square * * * * * "Pyramid" is the name given to a class of solid (3-dimensional) shapes whose base can be a polygon with any number of sides. All other faces are triangles which meet at the apex of the pyramid.
A pyramid has 4 faces. :D * * * * * Not quite. A pyramid is a generic term used to describe a polyhedron with a polygonal base and a number of triangles rising from that base to meet at an apex. A pyramid whose base is a polygon with n-sides (or vertices) has n+1 faces, n+1 vertices and 2n edges, where n ≥ 3.
