A hexadecahedron is a closed 3-d shape with 16 polygonal faces. There are almost 388 billion topologically different convex versions and, since none of these are regular, the term is ambiguous. The number of vertices will depend on which specific 16-hedron you have in mind.
HEXADECAHEDRON is the correct name for a 16 sided 3D object
A hexadecahedron is a closed 3-d shape with 16 polygonal faces. There are almost 388 billion topologically different convex versions and, since none of these are regular, the term is ambiguous. There are, therefore, 388 billion images, together with variations of each which can be created by stretching and skewing (twisting) the shapes.
Sixteen. If made from sides (facets) consisting of equilateral triangles, it has nine vertices (points or corners) and twenty-four edges. Unlike its first cousin the icosahedron, not all points are equidistant from the center of the solid.
Assuming it has 16 triangular sides plus a base making 17 faces in all, it would be a heptadecahedron. If it is a 16-faced shape then a hexadecahedron.Assuming it has 16 triangular sides plus a base making 17 faces in all, it would be a heptadecahedron.
