Use this 3D Objects Worksheet to assist your students when learning about the properties of 3D objects.
Explore 3D Objects and Their Properties
This worksheet allows your students to identify a variety of common 3D objects and their properties. There are two versions of the resource, which are outlined below:
- Version 1 – Students must name the object, then record the number of faces, edges and vertices.
- Version 2 – Students must name the object, then record the number of faces, edges, vertices, flat surfaces and curved surfaces.
The 3D objects included in this worksheet are: cube, rectangular prism, cone, triangular pyramid, cylinder, square pyramid and triangular prism.
A Note About Cones and Cylinders
If you look at the answer sheet to this resource, you will notice the following properties are attributed to cones and cylinders:
- Cones – Faces (0), Edges (0), Vertices (0)
- Cylinders – Faces (0), Edges (0), Vertices (0)
If this seems strange to you, then please read on for an explanation!
In geometry, the following definitions apply for faces, edges and vertices:
- Face – A flat surface with straight edges.
- Edge – A straight line formed by two faces meeting.
- Vertex – The point where two or more edges meet.
According to these definitions, a cone has no faces, edges or vertices. It has one flat surface, one curved surface and one apex.
Similarly, according to these definitions, a cylinder has no faces, edges or vertices. It has two flat surfaces and one curved surfaces.

Hello, I wonder why you do not include the properties of the cone and the cylinder in this resource?
Hi Kylie-Anne, Thanks for your comment. I believe I understand what you are putting forward here. The properties of cones and cylinders remain a point of conjecture and we even have a blog about it! https://www.teachstarter.com/au/blog/cone-cylinder-debate/ If you have a suggestion for a change, you can submit a change request to this resource using the Changes & Updates tab above. This tab can be found near the comments section. Thanks again!
