## 'Fill Me up Too' printed from http://nrich.maths.org/

Imagine a conical container that contains a volume of 10cm$^3$ when
filled to a height of 1cm:

Height |
Volume |

1 |
10 |

2 |
80 |

3 |
270 |

What is the relationship between the height and volume as this cone
is filled?

How could you draw a graph to show this?
