Elongated triangular bipyramid

An elongated triangular bipyramid is a type of polyhedron that can be categorized as an Archimedean solid. It is formed by taking a triangular bipyramid and extending it along its vertical axis, effectively stretching it. To understand its structure, consider the following: - A standard triangular bipyramid is created by joining two tetrahedral pyramids base to base, which results in a shape that has six vertices, nine edges, and eight triangular faces.
