volume= length times width times hight.
mililiters
Cubic centimetres.
A ruler. Measure one of the sides, and take that measurement times itself three times, and you'll have the volume.
Probably a cubic centimetre.
I wiil use water
You can not measure the volume of a liquid with a measurement designed to determine length. A centiliter is a measurement of volume, or the amount of space that a liquid can consume inside an object. A centimeter, would be a measurement of length and a centigram is a measurement of mass (weight).
Each side would measure 7 centimetres.
The metric measurement used to measure volume is the liter (L).
It matters what you are trying to measure. For instance the largest for distance would be different than for volume.
Many units are used to measure volume; in SI, the basic unit would be cubic meters, since lengths are measured in meters.
They would use density to measure the volume of a substance :)
In the metric system, the units of measurement of Volume is the Liter (sometimes spelled Litre) and the measurement for mass would be the gram. In the American system, the units of measurement for Volume is the ounce, and for mass would be the pound.
