This 3d shape has 12 faces?
A dodecahedron. A dodecahedron is any polyhedron with twelve faces, but usually a regular dodecahedron is meant. It is a Platonic solid composed of twelve regular pentagonal faces, with three meeting at each vertex. It has twenty (20) vertexes and thirty (30) edges. The dodecahedron would be the Platonic solid with the largest volume if all were made with edges of the same length.
What are facts about a dodecahedron?
it is a platonic shape and it has 12 faces 20 vertices and 30 edges
What is a 3D five sided shape?
A 3D 5 sided shape is called a dodecahedron. It is a solid with 20 vertices, 30 edges and 12 equal pentagonal triangular faces.
What shape can have a triangular base and triangular faces?
A triangular prism, a triangle base and three triangular faces (a tetrahedron)The figures below do not strictly have a "base" but they are composed entirely of trianglesAn octohedron (eight sides)An isocahedron (20 identical equilateral triangular faces, 30 edges and 12 vertices)Any of a number of deformations of the above
What is the collective name of these solids tetrahedron cube octahedron dodecahedron?
Together with icosahedron (20 faces) they are known as the Platonic Solids.
