Watch: a kettle holding 3 litres and 75 ml of water
Another worked example
Two identical bottles and a jug each carry a scale that starts at 0 at the bottom. Each bottle's top mark is labelled 300 ml with six equal gaps below it. The jug's top mark is labelled 1 ℓ 200 ml with eight equal gaps below it. None of the other marks is labelled. The water in the first bottle stands at the fifth mark above the bottom, the water in the second bottle at the second mark, and the water in the jug at the third mark. (a) Find the volume of water in the jug at first. (b) All the water in the two bottles is poured into the jug, without any spilling. How much water is in the jug in the end? Give your answer in litres.

Try it yourself
Use the equal relationship between cubic centimetres and millilitres.
A fish tank holds 2500 cm³ of water. What is the volume of the water in litres?
Ans: 2.5 ℓ
