Faces are the surfaces on the outside of a shape. Edges are the lines where two faces meet. Vertices or corners are where two or more edges meet. The properties of a 3D shape are the number of faces, edges and vertices that it has. The above 3D shape is a cuboid, which is box shaped object. A cuboid has 6 rectangular faces, which are the outside surfaces of a 3D shape.

A cuboid has 12 straight edges, which are the lines between the faces. A cuboid has 8 vertices, which are its corners where the edges meet. 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. Example Video Questions Lesson. What are the Properties of 3D Shapes? The properties of 3D shapes are faces, edges and vertices.

Faces are the flat or curved surfaces that make up the outside of a 3D shape. Edges are the lines where two faces on a 3D shape meet.

Vertices are the corners of a 3D shape formed where two or more edges meet. For example, a cube has 6 faces, 12 edges and 8 vertices. The poster below shows the faces, edges and vertices of 3D shapes labelled on a cube. All three dimensional shapes have the the three dimensions of length , width and depth. A shape is 3D if it can be picked up and held in real-life.

When teaching the properties of 3D shapes, it is worth having a physical item to look at as you identify and count each property. There are also printable nets for each 3D shape above that can be downloaded and assembled to accompany this lesson. Alternatively, there are some online interactive 3D shapes in the practice section above that you can use to count the faces, edges and vertices. When teaching this topic, it can be helpful to count the number of each property on the net before assembling it.

You can colour in each face a different colour, or write a number from 1 — 6 on each square face. You can mark each edge as you count it by drawing a line on each one. You could put a sticker or piece of plasticine on each vertex as you count it.

Marking the faces, edges and vertices as you count them is important as it can be easy to count them twice or miss one out. Faces, Edges and Vertices of a Cube A cube has 6 faces, 12 edges and 8 vertices. Each face of a cube is a square. All of its edges are the same length. Each of the 6 faces of a cube is square-shaped because all of its edges are the same size. A cube is a 3D square. There are 12 edges on a cube, which are all the same length.

Knowing these properties for different three-dimensional shapes lays the foundation for various industries such as architecture, interior design, engineering and more. Answer: 6 faces. They can have 2 square faces and 4 rectangular faces or just 6 rectangular faces.

For all the common prisms cubes, cuboids, triangular prisms, pentagonal prisms and hexagonal prisms add the faces and vertices together and subtract the edges. What do you notice about the answers? Answer: The answer is always 2. Wondering about how to explain other key maths vocabulary to your children? Check out our Primary Maths Dictionary , or try these:.
