A short cut ! Volume = 6 x 3 x 4 = 72 cm³ Volume = length x breadth 21-Apr-17 3cm 4cm 6cm height Area of rectangle breadth length Volume = 6 x 3 x 4 = 72 cm³ Volume = length x breadth x height

Example 1 27cm 5 cm 18 cm Working Volume = l x b x h V = 18 x 5 x 27 21-Apr-17 Example 1 Working Volume = l x b x h Heilander’s Porridge Oats V = 18 x 5 x 27 V = 2430 cm³ 27cm 5 cm 18 cm

Example 2 2cm Working Volume = l x b x h V = 2 x 2 x 2 V = 8 cm³ 21-Apr-17 Working Volume = l x b x h V = 2 x 2 x 2 V = 8 cm³ 2cm
