Volume = 250 × 12 × 10 = 2500 × 12 Volume = 30 000 cm3**20 cm**1.5 m 2 m For a cuboid Volume = length × width × height or Volume = area of cross-section x length Example Sand in sandpit = 0.2m Think about…Which dimension should be converted? Volume = 2 × 1.5 × 0.2 = 3 × 0.2 = 0.6 Volume = 0.6 m3**Volume**• Reflect on your work A manufacturer needs to know the volume of a box (cuboid). Explain how to find this. What units can volume be measured in? Suggest dimensions that you could use to make a carton with a volume of 1 litre (1000 cm³).
