A 3D shape with 15 faces is called a "triskaidecahedron." Specifically, if all faces are triangles, it can be referred to as a triangular triskaidecahedron. In general, polyhedra with varying face shapes can also have 15 faces, but the term "triskaidecahedron" typically denotes a polyhedron with 15 faces.
