We are sure you would have seen candles. Generally, they are in the shape of a cylinder.
You may have also seen some candles shaped like an animal (see Fig. 13.17).
If you want a candle of any special shape, you will have to heat the wax in a metal container till it becomes completely liquid. Then you will have to pour it into another container which has the special shape that you want.
For example, take a candle in the shape of a solid cylinder, melt it and pour whole of the molten wax into another container shaped like a rabbit. On cooling, you will obtain a candle in the shape of the rabbit.
The volume of the new candle will be the same as the volume of the earlier candle.
This is what we have to remember when we come across objects which are converted from one shape to another, or when a liquid which originally filled one container of a particular shape is poured into another container of a different shape or size, as you see in Fig 13.18.
