It's an Octohedron, which has 8 triangular faces. Think of one of the great pyramids in Egypt, with a square base and four triangular sides. Take two of these, turn one upside down, and glue them together along the square base. You wind up with 8 triangular faces, and 12 edges!

If a polyhedron has 10 more edges than vertices how many faces does it have?
For all polyhedra: vertices + faces = edges + 2 The given fact is: edges = vertices + 10 → vertices + faces = vertices + 10 + 2 → faces = 12
There are 18 edges and 8 faces in a polyhedron. how many vertices does it have?
12 vertices A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges.
How many faces vertices and edges does a cuboid have?
By Euler's formula the number of faces (F), vertices (V), and edges (E) of any convex polyhedron are related by the formula F + V = E + 2. In the case of a cuboid this gives 6 + 8 = 12 + 2; that is, like a cube, a cuboid has 6 faces, 8 vertices, and 12 edges.
Which polyhedron has 12 vertices's and 18 edges?
eighthedron eighthedron
What figure has 6 faces and 12 edges?
A cube or a cuboid would fit the given description of 12 edges and 6 faces.
A polyhedron with 12 vertices and 30 edges has how many faces?
A polyhedron has 30 edges and 12 vertices. How many faces does it have
What is a polyhedron with 12 edges?
dodecahedron * * * * * A dodecahedron has 12 FACES, not 12 edges!
How many vertices's does a convex polyhedron have if it has 14 faces and 24 edges?
Using Euler's Polyhedron formula V+F-E=2, givenF=14 and E=24, we have V=12.The polyhedron has 12 vertices.This assumes a genus-0 polyhedron. An example would be the hexagonal antiprism, a polyhedron having two hexagonal faces and 12 triangular faces.

How many equal sides doea an icosahedron have?
An icosahedron is a regular polyhedron with 20 identical equilateral triangular faces, 30 edges and 12 vertices. It is one of the five platonic solids.

It has 6 vertices.
If a polyhedron has 10 more edges than vertices how many faces does it have?
