1 cm Volume = = 1 cm³ x hx b l How much water does this hold? A cube with volume 1cm³ holds exact 1 millilitre of liquid. A volume of 1000 ml = 1 litre. I’m a very small duck! Liquid Volume
Example 1 12 cm 6 cm 3 cm Orange Flavour Volume = l x b x h V = 6 x 3 x 12 V = 216 cm³ = 216 ml So the carton can hold 216 ml of orange juice. How much juice can this carton hold? Remember: 1 cm³ = 1 ml Working Liquid Volume
Example 2 50 cm 100 cm 30 cm Volume = l x b x h V = 100 x 30 x 50 V = cm³ = ml So the fish tank can hold 150 litres of water. How much water can this fish tank hold in litres? 1cm 3 = 1 ml 1000 ml = 1 litre = 150 litres Working Liquid Volume
