 Gyroelongated square cupola

The gyroelongated square cupola is a type of convex polyhedron that can be classified as a member of the Archimedean solids. It is formed by taking a square cupola, which consists of a square base topped by two triangular faces and octagonal faces, and then elongating it by adding two square pyramids (with their bases being the octagonal faces) above and below the square cupola.
