example, using a ruler to measure the diameter of a PVC pipe.

3. Volume: units of volume are used to measure the capacity of a container to hold/store, or the amount of

space an object occupies in three-dimensions. For example, a storage tank’s capacity to hold water would be

measured as a unit of volume.
