  1. Volumes of Prisms This is given by V = area X length Example 70m 4.6m2 V = area X length = 4.6 X 70 = 322m3

  2. Example 19cm 1.4cm 6cm ******** Area of triangle = b X h  2 V = area X length = 6 X 1.4  2 = 4.2 X 19 = 4.2cm2 = 79.8cm3

  3. CYLINDERS Base is a circle. Area of base = r2 Vol = area X height So V =r2h Example d = 8cm so r = 4cm, h = 50cm V =r2h = 3.14 X 4 X 4 X 50 = 2512 8cm = 2510cm3 50cm
