How to read the visual
The diagram uses the recorded measurements. Details outside the marked spans do not set the scale.
- The volume of a 25 ml measure: This is an illustrative comparison value, not a claim that every example is the same.
Volume measures three-dimensional space; a container’s capacity is not its outside dimensions.
