## How many surfaces does a ball have?

A sphere has no faces, a cone has one circular face, and a cylinder has two circular faces. Therefore, the number of faces increases by one from one figure to the next.

**How many vertices does a ball have?**

0 vertices

Spheres have 0 faces, 0 edges and 0 vertices.

### How many faces does a sphere have Twinkl?

1 face

Spheres actually have 1 face, 0 edges, and 0 vertices.

**How many faces edges does a sphere have?**

Solid Shapes | Faces | Edges |
---|---|---|

Definition | A face refers to any single flat surface of a solid object. | An edge is a line segment on the boundary joining one vertex (corner point) to another. |

Sphere | 1 | 0 |

Cylinder | 3 | 2 |

Cone | 2 | 1 |

#### What is the flat face of a cone called?

The pointed end of the cone is called the apex, whereas the flat surface is called the base.

**Does a cone have 1 or 2 faces?**

Instead, lead them to see that a cone only has one face, and you need more than one face to form an edge. Ask: Does a cone have any vertices? Lead students to see that a cone has no edges (at least no straight ones!), but the point where the surface of the cone ends is called the vertex of the cone.

## How many vertices a cone has?

A face is a flat surface. An edge is where two faces meet. A vertex is a corner where edges meet….Vertices, edges and faces.

Name | Cone |
---|---|

Faces | 2 |

Edges | 1 |

Vertices | 1 |

**Is a sphere a 2d or 3D shape?**

3D objects include sphere, cube, cuboid, pyramid, cone, prism, cylinder.

### What are properties of cylinder?

Describe the Properties of Cylinder.

- Cylinder has one curved surface, two curved edges, and two flat circular faces.
- The two flat circular bases are congruent to each other.
- A cylinder does not have any vertex.
- The base and the top of the cylinder are identical.

**Does a sphere have 1 edge?**

Edges. An edge is where two faces meet. For example a cube has 12 edges, a cylinder has two and a sphere has none.

#### How many edges has a cylinder got?

two

A face is a flat surface. An edge is where two faces meet. A vertex is a corner where edges meet….Vertices, edges and faces.

Name | Cylinder |
---|---|

Faces | 3 |

Edges | 2 |

Vertices | 0 |
