# What is the name of a 3d shape that has 6 faces 12 edges and 8 vertices?

It is a cuboid

It is a hexahedron, of which, a cuboid may be a more familiar example.

Tetrahedron 3 triangles meet at each vertex 4 Faces 4 Vertices 6 Edges Cube 3 squares meet at each vertex 6 Faces 8 Vertices 12 Edges Octahedron 4 triangles meet at each vertex 8 Faces 6 Vertices 12 Edges Dodecahedron 3 pentagons meet at each vertex 12 Faces 20 Vertices 30 Edges Icosahedron 5 triangles meet at each vertex 20 Faces 12 Vertices 30 Edges

### What is the name of five platonic solids?

1~Tetrahedron *4 faces (made of equilateral triangles) *6 edges *5 vertices 2~Hexahedron (cube) *6 faces (made of squares) *12 edges *8 vertices 3~Octrahedron *8 faces (made up of equilateral triangles) *12 edges *6 vertices 4~Icosahedron *20 faces (made of equilateral triangles) *30 edges *12 verticies 5~Dodecahedron *12 faces (made of pentagons) *30 edges *20 vertices.

### How do you figure out the edges in a 3D shape?

There is no simple way. You cannot go by the name - which can refer to the number of faces. You can have different shapes with the same number of faces. The following are all examples of a hexahedron (six faces): triangular dipyramid (9 edges), pentagonal prism (10 edges), rectangular prism (12 edges). One contributor has suggested it might be easier to count the faces and vertices (corners). Add the two numbers and then subtract…

### How many faces vertices and edges on a dedocahedron?

As the name implies, there are 12 faces on a dodecahedron. Each face is a pentagon, which has 5 edges, so there would be 60 edges altogether except that each edge is shared by 2 faces, so there are 30 edges. Using Euler's formula V + F = E + 2, the number of vertices is 20. Therefore each vertex is shared by 3 faces and 3 edges.

### What two different shapes have 6 faces 12 edges and 8 vertices?

One is a cuboid. The other is a shape with two pentagonal shapes that meet along one edge. Along the next edges, one on either side is a triangular face. And on the further two sides of the pentagon are trapezium faces. I am not aware of a name for this shape other than hexahedron, which does not distinguish it from a cuboid.

### How many vertices does a pentahedron have?

There are five vertices on a pentahedron. The word penta means five which is based on the 5 edges and 5 diagonal faces that it has. * * * * * Apart from the fact that penta means five, the rest of the answer is utter nonsense. Typical of answers from "The Community", I am afraid. 5 vertices 5 faces 8 edges

### How can we find faces with the help of vertices and edges?

To find faces of 3-d shape if the value of vertics and edges is given, is very easy. For this process I've invented a formula which is: Formula invented by, Xxxxx Xxx (name removed as per Answers.com rules) * * * * * Not so! The relationship was actually found by Leonhard Euler, who lived in the 18th Century! Plus, your spellings leave something to be desired: Vertices (not vertics) Icosahedron (not icosahydron).

### How many faces vertices and edges does a hexagonal prism oCtagonal prism n-gonal prism triangular pyramid rectangular pyramid pentagonal pyramid hexagonal pyramid n-gonal pyramid?

Name Edges, Faces, Vertices Hexagonal Prism 18, 8, 12 Octagonal Prism 24, 10, 16 A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges. Triangular Pyramid 6, 4, 4 Rectangular Pyramid 8, 5, 5 Pentagonal Pyramid 10, 6, 6 Hexagonal Pyramid 12, 7, 7 A pyramid with an n-sided base will have n + 1 vertices, n + 1 faces, and 2n edges.

### How many corners has a icosahedron have?

The name most mathematicians use for the corners is vertices. An icosahedron is a 20 sided polyhedron. It is one of a group of special solids known as platonic solids. So, the icosahedron has 20 faces and 12 vertices or "corners" as you call them. It has 30 edges. There is an interesting formula that relates the number of edges, vertices and faces. V+F-2=E where V is the number of vertices, F the number of…

### Prism how many edges and vertices?

a prism always have 6 or 8 edges and vertices learn math dang * * * * * Good point! Learn math - or maths even. A prism is a generic name for a 3-d shape with two congruent polygonal "bases" with n-sides each, and n rectangles joining them together. That means a prism with a n-polygon base has 3n edges and 2n vertices.
