How many millimeters are in10 metters?

Answer 1

You cannot directly associate length and volume. If you want to do this, you need the shape and likely other dimensions. Furthermore, before using a volume formula, you are best to convert all units to centimetres (divide by 10) to end up with centimetres cubed, which is millilitres.

Answer 2

There are 1000 millimetres in a metre. This means that you multiply metres by 1000 to get an answer in millimetres. You have 10*1000, giving you 10,000 millimetres.
