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?

What is the collective name of these solids tetrahedron cube octahedron dodecahedron?
Together with icosahedron (20 faces) they are known as the Platonic Solids.
What is each platonic solid made of?
Each Platonic solid is composed of congruent regular polygons as its faces, with the same number of faces meeting at each vertex. There are five Platonic solids: the tetrahedron (4 triangular faces), cube (6 square faces), octahedron (8 triangular faces), dodecahedron (12 pentagonal faces), and icosahedron (20 triangular faces). These shapes are characterized by their symmetry and uniformity, making them fundamental in geometry.
How many regular 3d shapes are there?
There are five Platonic solids: Tetrahedron (or triangular pyramid): 4 triangular faces Cube: 6 square faces Octahedron: 8 triangular faces Dodecahedron: 12 pentagonal faces Icosahedron: 20 triangular faces. Although not a Platonic solid, some people consider a sphere to be a regular 3d shape.
How many Platonic Solids are there?
There are 5. They are the tetrahedron (4 triangular faces), the cube (6 square faces), the octahedron (8 triangular faces), the dodecahedron (12 pentagonal faces), and the icosahedron (20 triangular faces).
What is the name of a solid with 20 faces?
A solid with 20 faces is called a icosahedron. It is one of the five Platonic solids and is characterized by its twenty equilateral triangular faces, 30 edges, and 12 vertices. The icosahedron is often used in geometry, gaming, and various applications in science and art.
What do the platonic solids look like?
The Platonic solids in modern Euclidean geometry are five regular polyhedra. These are three-dimensional objects that are bounded by regular polygonal faces. They are: Tetrahedron (or triangular pyramid): 4 triangular faces; Hexahedron (cube): 6 square faces; Octahedron: 8 triangular faces; Dodecahedron: 12 pentagonal faces; Icosahedron: 20 triangular faces. See link for more.
How many equal sides an icosahedron have?
An icosahedron has 20 triangular-shaped faces.
What platonic solid has pentagons for faces?
The platonic solid that has pentagons for faces is the dodecahedron. It consists of 12 regular pentagonal faces, 20 vertices, and 30 edges. The dodecahedron is one of the five Platonic solids, which are characterized by their faces being congruent regular polygons meeting at each vertex.
What are platonic solids and what do they look like?
The five Platonic solids are regular polyhedra. They are convex shapes which are created from regular polygonal faces, such that the number of faces meeting at each face is the same.The five are:tetrahedron - 4 triangular faces;hexahedron (or cube - 6 square faces;octahedron - 8 triangular faces,dodecahedron - 12 pentagonal facesicosahedron - 20 triangular faces.To see their images, search Google for Platonic Solids.
What is a solid figure with twenty faces called?
The regular solid, with 20 identical equilateral triangular faces, is called an icosahedron.
How many faces does a polyhydra triangle have?
There are several triangular polyhedra. The simplest is a tetrahedron with 4 faces, but you can have a triangular dipyramid (two tetrahedra stuck together along one face) which has 6 faces. Then there is the icosahedron with 20 faces. The tetrahedron and icosahedron are Platonic solids, but there are many more.
What are the Platonic Solids and what do they look like?
The Modern Five Platonics are ( quite different than the originals known to Plato and Kepler, are in art classes: Sphere, cube, cone, cylinder, and Pyramid. Tetrahedron is another word for the last-named solid. it was a virtual connundrum in art classes that they were basic, required material and the theory was nobody could draw in perspective without this background. Jon Gnagy among others pushed the 5 Platonic solids in his art courses on TV. of course if one is drawing monuments, it is obvious.They were the type of thing that was popular with teachers not so popular with students.
What are the 5 names of the platonic solid?
Tetrahedron (4 faces), Cube (6), Octahedron (8), Dodecahedron (12) and Icosahedron (20).
