How many edges do 3D shapes have?
Vertices, edges and faces
| Name | Faces | Edges |

| Cuboid | 6 (all rectangles) | 12 |
| Cylinder | 3 | 2 |
| Cone | 2 | 1 |
How many faces and edges do 3D shapes have?
3-D Solids: Faces, Edges and Vertices

Can a 3D shape have equal numbers of vertices edges and faces?
The properties of a 3D shape are the number of faces, edges and vertices that it has. A cuboid has exactly the same number of faces, edges and vertices as a cube. A cuboid is different from a cube in that its edges are longer in at least one direction, whereas a cube has edges that are all equal in length.
What do all 3D shapes have in common?
3D shapes have three dimensions – length, width and depth.
Can an edge be curved?
An edge is the place where two faces meet. Edges are straight; they cannot be curved.
Which of the shape have no vertex or edges?
A sphere is a solid figure that has no faces, edges, or vertices. This is because it is completely round; it has no flat sides or corners. A cone has one face, but no edges or vertices. Its face is in the shape of a circle.
Does a cone has 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.
Which shape has 3 more edges than vertices?
The base of a triangular prism has 3 edges. It therefore has 3 side faces plus the base and top, or 5 in all.
