A pentahedron.
icosahedron (its a 20 sided trinagular faced polyhedron)
A heptahedron is a polyhedron with 7 faces, and you can make one with 15 edges.
A polyhedron is a solid figure with many plane faces, usually greater than six. A polyhedron that has 7 faces is called a heptahedron.
Nope - A polygon is a flat, 2-dimensional shape. A Polyhedron is a 3-dimensional shape.
A polyhedron with 5 faces could be called a pentahedron, but a more common name would be a quadrilateral pyramid. A square pyramid is a special case of such a shape.
A dodecahedron is a twelve-faced polyhedron.
A tetradecachedron is a polyhedron, also known as a 14-sided polyhedron or 14-faced polyhedron. It is a convex solid with 14 faces, 24 edges, and 14 vertices. The term "tetradecachedron" can refer to any 14-faced polyhedron, not necessarily a specific shape.
It could be a non-polyhedral shape. If it is a polyhedron, it can be a quadrilateral based pyramid or a triangle based prism.
icosahedron (its a 20 sided trinagular faced polyhedron)
An 8-faced 3D shape is called an octahedron. It is a polyhedron with eight triangular faces, 12 edges, and six vertices.
A heptahedron is a polyhedron with 7 faces, and you can make one with 15 edges.
A polyhedron is a solid figure with many plane faces, usually greater than six. A polyhedron that has 7 faces is called a heptahedron.
A polygon (2-dimensional shape) with 10 sides is a decagon. A 3-dimensional polyhedron with 10 faces is a decahedron.
A polyhedron is a 3-dimensional shape whose faces are all polygons.
A polyhedron is a geometric shape. It does not have the capability of doing anything.
no it's a polygon not a polyhedron
Nope - A polygon is a flat, 2-dimensional shape. A Polyhedron is a 3-dimensional shape.
