  1. An Introduction to 3-D Shape Slideshow 16, Mathematics Mr Richard Sasaki Room 307

  2. Objectives Recall names of certain elements of basic shapes Recall formulae to find attributes to certain basic shapes Apply these formulae to finding missing values for shapes

  3. 3-D Shapes Triangular Prism Cuboid(Rectangular Prism) Cylinder Cube

  4. The Cube (length)3 Volume (V) = V = 3 = A cube has 6 square faces where 3 meet at each vertex.

  5. The Cuboid Volume (V) = length × width × height V = = = = A cuboid has 6 rectangular faces where 3 meet at each vertex.

  6. Example Let’s label the values given on the cuboid. = You will now receive your information sheet. Please use it for the worksheets given. = = A cuboid has width and height 3cm. It’s volume is 63cm3. Calculate its length, .

  8. The Cylinder Volume (V) = V = = = The cylinder is made up of two parallel circles connected by a curved edge.

  9. The Triangular Prism ½ × base × height × length Volume (V) = V = = = = A prism made of two triangles and three rectangles.

  10. Example Let’s label the values given on the prism. V = Try the last worksheets! V = V = A triangular prism has base 5cm, height 10cm and length 12cm. Calculate its volume.
