How many sides in a quadrahedron?

Answer 1

A quadrahedron has 5 faces. One face (the base) is four sided. The remaining 4 faces are triangular. It is commonly envisioned as a four sided pyramid. A tetrahedron has 4 faces, all triangular. It is commonly envisioned as a three sided pyramid.

Answer 2

There are Five(5) faces; four triangles on the surface, and one face on the bottom.

Answer 3

Using "quadrahedron" to designate a 5-sided polyhedron is a misnomer, and commonly used wrongly.

The Greek prefix "quad" means 'four". A quadruped has four legs.

A pyramid having four sides and a base is a pentahedron, because it has five sides. The 'base" is a side, and "base" is an arbitrary designation.

A tetrahedron is a quadrahedron.
