  1. The Fourth Plinth Polyhedral Life

  2. Theme:The Olympics Task: Design a sculpture linked to the Olympics using polyhedra. Background: The fourth plinth in Trafalgar Square is an empty pedestal that has been empty since 1841. Over the past number of years there has been a changing exhibition of different sculptures on it, including Anthony Gormley's "The One and the Other". Over 100 days, members of the public stood on the plinth 24 hours a day.

  3. Your structure needs to take the place of the cowboy picture What dimensions does it need to be?

  4. Polyhedra Here are a selection of polyhedra you may wish to consider in your planning Cuboid Cube Triangular prism Hexagonal prism Pentagonal prism Octagonal prism Cylinder

  5. Materials • When you make your model/sculpture, you can choose to construct it from a wide variety of materials. These may include the following: • Carving of wood, stone, plaster and cement • Welding of metal (steel and copper) plates • Twisting and wrapping of wire • Modeling of forms in clay, wax and plaster • Casting of bronze, steel and plastic • Working in iron and copper • Blowing or moulding of glass • The following slide shows examples of statues made from different materials to give you an idea of the finish and aesthetic qualities of your model/statue.

  6. Copper Marble Sheet Metal Bronze Examples of how different materials are used to create sculptures Perspex Glass Granite Sheet Metal Iron

  7. Costs In the table below are the costs of a selection of materials, from which you may choose to make your model/statue. They have been split into whether you need to calculate the volume or the surface area N.B. Where the cost has been given in terms of weight (i.e per Kg), you will need to use the density of the material in your calculations.

  8. Fourth Plinth Submission Please affix a photograph of your model here Title of Submission: Materials to be used: Estimated amount of material required: (please provide calculations on a separate sheet) Estimated cost of structure: Please provide an explanation of the vision/story behind your choice of structure: Submitted by:

  9. Formulae you may need to know To find the surface area of a shape, find the area of each face and add them together. Area of: • Rectangle = length × width • Triangle = 1/2 base × height • Circle = πr² • Trapezium = 1/2 (a + b) × vertical height (where a and b are the two parallel sides) • Surface area of sphere = 4 πr² Volume of: • Cuboid = length × width × height • Prism = area of cross-section × height • Cylinder = πr² h • Cone =1/3πr² h • Pyramid = 1/3 × base area × height • Sphere = 4/3πr²

  10. Enlarging your design to estimate materials needed and cost To be able to estimate the quantity of materials needed and the costing involved, you first need to be able to work out the enlarged dimensions. General Rule • If the lengths in a shape or solid are all multiplied by a scale factor of k, then the areas will be multiplied by a scale factor of k² and the volumes will be multiplied by a scale factor of k³. • For example, if the lengths are enlarged with scale factor 4, then the areas will be enlarged with scale factor 16 and the volumes will be enlarged with scale factor 64.

  11. Plan of action • Draw a sketch of the sculpture you would like to make • What polyhedra could you use to create your sculpture? • How much paper, card or other material will you need? What other resources will you require? • Split the project up into individual tasks within your group and decide who is responsible for each task • Work out how much it will cost to make your sculpture using the costing sheet • Complete the submission form to bid for your sculpture to appear on the plinth

  12. Extended Polyhedra Sphere Cuboid Dodecahedron Tetrahedron Icosidodecahedron Cube Octahedron Square based pyramid Triangular prism Here are a selection of polyhedra you may wish to consider in your planning Pentagonal prism Cuboctahedron Octagonal prism Icosahedron Cone Cylinder Hexagonal prism

  13. Pyramids and Cones Volume = 1/3 x area of base x height

  14. Other polyhedra and spheres

  15. A few semi-regular polyhedra
