# How many cubic millimetres (mm) are in a cubic nanometre (nm)? Watch

1. How many cubic millimetres (mm) are in a cubic nanometre (nm)?

Express your answer as an index (such as: 10^99)

1 nm3 = 10^-- mm3

You can start by asking yourself how many millimetres are in a nanometre, and then cube your answer.

Or if you need to take a step further back:
Consider how many nanometres are in a millimetre, and hence by inverting that how many millimetres are in a nanometre.

See what you can do.

Think of the way you obtain volume from lengths. Using that, I would write each prefix in SI units and substitute into the formula to get the answer you are looking for. I don't want to give you the answer straight away.
4. Convert both to cubic metres.

Remember the rules for indices when multiplying or dividing two numbers of the same base.

So 1cm^3 = 1x10^-9 m^3

and 1nm^3 = 1x10^-27 m^3

Careful with the -ve signs.

1 cm = 10^-2 m

Oooops hahha.

My bad

1 cm^3 = 10^-6 m^3
