An introduction to 3D shapes SOLIDS An introduction to 3D shapes

You should recognise all of these solids: Cube Cuboid Prism Cylinder Pyramid Cone Sphere

Cube Six square faces Edges: 12 vertices: 8 Common example: dice

Cuboid Six rectangular faces Edges: 12 vertices: 8 Common example: boxes

Prism Cross-sectional area is the same all through the shape. Faces: 5 edges: 9 vertices: 6 (for a triangular prism) Common example: Toblerone box

Cylinder Cross-sectional area is a circle. Faces: 3 edges: 2 vertices: 0 Common example: soup tin

Pyramid Base is a polygon. Sides meet at a point Faces: 5 edges: 8 vertices 5 (for a square-based pyramid) Common example: Egyptian pyramids

Cone Base is a circle, narrowing to a point Faces: 2 edges: 1 vertices: 1 Common example: some ice cream cones

Sphere Completely round solid Faces: 1 edges: 0 vertices: 0 Common example: football
