## How many edges does an object have if it has 7 faces and 10 vertices

15 edgesThere are 7 faces, 15 edges, and 10 vertices. We know, as per Euler’s polyhedron formula; V – E + F = 2.

## Can a polyhedron have the same number of faces edges and vertices

Figure 6: Both these polyhedra have ten faces, but neither has seventeen vertices. … The second feature, called regularity, is that all the solid’s faces are regular polygons with exactly the same number of sides, and that the same number of edges come out of each vertex of the solid.

## Can a polyhedron have for its faces 4 triangles

(ii) Yes, 4 triangles can be the faces of a polyhedron.

## Can a polyhedron have 10 faces 7 vertices and 15 edges

In geometry, the pentagonal prism is a prism with a pentagonal base. It is a type of heptahedron with 7 faces, 15 edges, and 10 vertices.

## Can a polyhedron have 12 faces 15 edges and 20 vertices

Hence it is not possible to have such polyhedron. …

## How many faces does a tetrahedron have

4Tetrahedron/Number of faces

## Can a polyhedron have 12 faces 22 edges and 17 vertices

Answer. Answer: No polyhedron has 12 faces, 22 edges, and 17 vertices.

## Which is not a polyhedron

Non-polyhedrons are cones, spheres, and cylinders because they have sides that are not polygons. A prism is a polyhedron with two congruent bases, in parallel planes, and the lateral sides are rectangles.

## What is the formula for faces edges and vertices

This page lists proofs of the Euler formula: for any convex polyhedron, the number of vertices and faces together is exactly two more than the number of edges. Symbolically V−E+F=2. For instance, a tetrahedron has four vertices, four faces, and six edges; 4-6+4=2.

## How many faces does a polyhedron have if it has 45 edges and 30 vertices

There are 17 faces in polyhedron.

## What will be the number of faces if there are 6 vertices and 12 edges

eightAnswer. Answer: In geometry, an octahedron (plural: octahedra) is a polyhedron with eight faces, twelve edges, and six vertices.

## Can a polyhedron have 15 faces 30 edges and 20 vertices

Answer. hence a polyhedron cannot have 15 faces 20 vertices and 30 edges.

## Can a polyhedron have 12 faces 18 edges and 20 vertices

Answer: No, it cannot have the given. Where F is number of faces, V the number of vertices and E the number of edges. Therefore the polyhedron cannot have the given.

## Can a polyhedron have 20 faces 40 edges and 30 vertices

Answer. therefore there is no polygon with 20 faces, 40 edges and 30 vertices.

## Can a polyhedron have 12 faces 24 edges and 20 vertices

Answer: A POLYHEDRON CANNOT HAVE 12 FACES, 20 EDGES AND 14 VERTICES.

## Can polyhedron have 10 faces 20 edges 15 vertices

Euler;s formula can’t be proved. Hence,a polyhedron can not have 10 faces,20 edges and 15 vertices.

## Can a polyhedron have 8 faces 20 edges and 15 vertices

Answer Expert Verified No.It can’t have 10 faces , 20 edges, and 15 vertices as The formula i.e. Euler’s formula isn’t being satisfied. … Therefore,A polyhedron cannot have 10 faces , 20 edges, and 15 vertices.
