Let's see how you got on:
- What is 4 m³ in dm³?
There are 1,000 dm³ per m³ so the answer is 4,000 dm³
- How many litres of wine will fit inside a barrel of 0·75 m³?
1 litre is 1,000 cm³. 1 m³ is 1 million cm³, so the answer is 750 L.
- A box has an area of 40 cm² and volume 600 cm³. How tall is it?
Its volume = area × height, so height = 600 ÷ 40 = 15 cm
You will need to learn the different formulas required to find the volumes of different shapes.
