Solution
Some of the reasons for difference in their measurement could be:
- Different measuring devices were used.
- The smallest length that could be measured by different devices may be different.
- Measurement may not be along the shortest length in all three cases.
- The end of the corridor may not be easily accessible.
- The measuring devices may be faulty (not standardised).
