## What is a shape with no corners?

A sphere has no edges and therefore no corners. It has one curved face that goes all the way around.

## Do cones have corners?

A cone is defined as a shape which is hollow or solid from inside and has a circular base that tapers at the upward point of the shape, which is known as the vertex. Some people might confuse the vertex of the cone with a corner but that is not the case. A cone will have one face and one edge but without a corner.

## What shape has 6faces?

A hexahedron (plural: hexahedra) is any polyhedron with six faces. A cube, for example, is a regular hexahedron with all its faces square, and three squares around each vertex.

## What is a curved face on a 3D shape?

Spheres are often referred to having one face, cones two faces and cylinders three faces. Mathematically a face on a 3D shape is part of a plane and therefore is flat. We have had a discussion about explaining that a sphere has a curved surface; a cone has 1 face and 1 curved surface etc.

## Does 9 edges have 6 vertices?

Answer and Explanation: A geometrical shape that has 6 vertices and 9 edges is a triangular prism.

## Has 2 triangular bases 3 rectangular faces 6 vertices and 9 edges?

A triangular prism is a polyhedron, (three-dimensional shape) made up of two triangular bases and three rectangular sides. Like other Prisms, the two bases here are parallel and congruent to each other. It has 5 faces, 6 vertices and 9 edges in total.

## What 3d shape has 3 faces and 2 Edges?

Vertices, edges and faces

Name Faces Edges
Triangular-based pyramid 4 6
Cuboid 6 (all rectangles) 12
Cylinder 3 2
Cone 2 1

## What 3D shape has 7 faces 15 edges and 10 vertices?

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.

## How many vertices does a polygon have if it has 10 faces and 15 edges?

Answer: Since the Euler’s formula does not hold true for the given number of faces, edges and vertices, therefore, there does not exist any polyhedron with 10 faces, 20 edges and 15 vertices.

heptahedron

## Could a polyhedron exist with 10 faces 7 vertices and 15 edges?

This solid is also a polyhedron. The bases are both pentagons, so it is a pentagonal prism. There are 7 faces, 15 edges, and 10 vertices.

## Can a polyhedron have 10 faces 20 edges and 15 vertices?

Q8. Can a polyhedron have 10 faces, 20 edges and 15 vertices? Hence,a polyhedron can not have 10 faces,20 edges and 15 vertices.

## Can a polyhedron have 10 faces 23 edges and 15 vertices?

No way. A polyhedron cannot have 10 faces, 23edges,15 vertices.

## Can a polyhedron have 20 faces 12 vertices and 30 edges?

Answer: According to the formula given by Euler. Therefore, there are 30 edges of a polyhedron having 20 faces and 12 vertices.

## What will be the number of edges if there are 12 vertices and 20 faces * 1 point 32 28 30 42?

Answer. Answer: According to the formula given by Euler. Therefore, there are 30 edges of a polyhedron having 20 faces and 12 vertices.

## How many faces does a polyhedron have if it has 12 vertices and 30 edges?

Polyhedra

Name # of Faces # of Edges
Cube 6 12
Regular Octahedron 8 12
Regular Dodecahedron 12 30
Regular Icosahedron 20 30

8 faces

cube

## How many edges a solid has?

It has 5 faces, 5 vertices, and 8 edges.

## Which solid has the greatest number of faces?

Properties of Icosahedron: It is one of five platonic solids that have equilateral triangular faces. An Icosahedron has 20 faces, 30 edges, and 12 vertices. It has the greatest volume for its surface area of any platonic solid. It has the greatest number of faces of any platonic solid.
