What does it mean to measure something? Does this explanation work equally well for length, area, weight, volume, and time?

What will be an ideal response?

1. Decide on the attribute to be measured.

2. Select a unit that has that attribute.

3. Compare the units—by filling, covering, matching, or using some other method—with the attribute of the object being measured. The number of units required to match the object is the measure.
