Exploring 3D Shapes: Cube, Sphere, Pyramid, Cone

Learn about the properties of different 3D shapes such as the cube, sphere, pyramid, and cone. Understand the number of faces, vertices, and edges in each shape. Play a game to match the shapes based on their shared faces.

  1. 3-D SHAPE

  2. What is a 3-D Shape? This is a cube height depth length It has 3 dimensions – length, height and depth. All 3-D shapes are solids.

  3. Labelling the Parts of a 3-D Shape A Cube Edge – a line where two faces meet Face – the flat surface of a 3-D shape A cube has: 6 faces 8 vertices 12 edges Vertex (vertices) – the point where three or more faces meet (corner)

  4. The Shapes you need to Know SPHERE SQUARE-BASED PYRAMID CONE Click on each shape to find out more about it! CUBE CYLINDER Look at this one first! TRIANGULAR PRISM REGULAR TETRAHEDRON CUBOID

  5. Cuboid Key Feature Six faces which are all rectangles. Faces 6 Vertices 8 Edges 12 Can you work out how many faces, vertices and edges I have? Click to check your answers… Click on me to check out other shapes…

  6. Cube Key Feature Six faces which are all squares. Faces 6 Vertices 8 Edges 12 Remember to work out how many faces, vertices and edges I have before clicking to check your answers…

  7. Triangular Prism Key Feature A prism with a triangular cross-section. Faces 5 Vertices 6 Edges 9 What’s a prism? Click here to find out…

  8. Prisms • A prism is a special kind of 3D shape . • Prisms have two ends which are exactly the same shape and size. • If a prism is sliced parallel to one of its ends then the new exposed ends will be exactly the same as the old ones. • A prism is the same shape and size all the way through. Examples of prisms: Hexagonal Prism Triangular Prism

  9. Regular Tetrahedron Key Feature Four faces which are all equilateral triangles. Faces 4 Vertices 4 Edges 6

  10. Sphere Key Feature Every point on the surface of the sphere is the same distance from the centre. Faces, Vertices and Corners The normal definitions of faces, vertices and edges are not appropriate for a sphere

  11. Cylinder Key Feature A prism with a circular cross-section. Faces, Vertices and Edges The normal definitions of faces, vertices and edges are not appropriate for a cylinder.

  12. Cone Key Feature The point of the cone is directly above the centre of the circular base. Faces, Vertices and Edges The normal definitions of faces, vertices and edges are not appropriate for a cone.

  13. Square-Based Pyramid Key Feature Faces 5 A shape with a square base and triangular sides that meet at a point. Vertices 5 Edges 8

  14. Nets of 3D Shapes

  15. Check this out! • 3D Shapes 1 - this is a game of matching pairs. • Can you arrange the shapes below in a chain so that each one shares a face (or faces) that are the same shape as the one that follows it? (The faces do not have to be the same size.)
