  1. Volume of Cuboids How many small cubes are in each of these cubes / cuboids? a b c d Starter: 4 cubes 8 cubes 6 cubes 12 cubes e f g h 16 cubes 27 cubes 45 cubes 64 cubes Investigation Other than counting the number of cubes, is there a mathematical way to work out the number of cubes in each cube / cuboid?Is it quicker than counting?

  2. Volume of Cuboids How many small cubes are inside this larger cuboid? Is there a quicker way to work out the number of cubes? Intro: 4 x 3 x 5 = 60 cubes 3 cubes 5 cubes 4 cubes How many small cubes are inside this larger cuboid? 7 x 4 x 6 = 168 cubes 4 cubes 6 cubes 7 cubes

  3. Volume of Cuboids Volume is the amount of 3–dimensional space an object occupies. Units of volume – mm3, cm3, m3 etc. Volume: A volume of 1cm3 is a cube of size 1cm by 1cm by 1cm 1cm 1cm 1cm Work out the volume of these cuboids if each small cube has a volume of 1cm3. 4 x 2 x 3 = 24cm3 6 x 2 x 6 = 72cm3 5 x 5 x 5 = 125cm3

  4. Volume of Cuboids How can we work out the volume of a cuboid? Volume of a cuboid = Length x width x height Volume: V = l x w x h Height (h) Length (l) Width (w) Work out the volumes of these cuboids. 6 x 10 x 4 = 240cm3 3 x 4 x 3 = 36cm3 4cm 3cm 6cm 3cm 4cm 10cm
