Unit 4 – lines and shapes
Describing and drawing 3D shapes
Solid shapes are three-dimensional (3D). We can pick them up. Here is a cube and a cuboid. 12 edges
6 faces
8 vertices
Both the cube and cuboid have the same number of faces, edges and vertices. What is different about the shape of their faces and the length of their edges?
1 Let’s look at the similarities and differences between these shapes.
cylinder
sphere
cone
All the shapes have curved faces. The cylinder has two flat circular faces but the cone only has one. The cylinder has two curved edges but the cone has one. Can you think why? The sphere does not have any flat circular faces or curved edges.
