why can a hand span or cubit not be used as a Standard tool for measuring length
Answers
Answer:
Explanation:
Hand span and cubit cannot be used as a standard unit of length . This is because these are not particular measurements . Like the hand span will vary from person to person and the true value would not be same . ... This is because the distance between them is very large and millimeters are a very small unit of length .
The cubit is a historic measurement that was never exactly defined, there are two main accepted lengths for it, at 14 and 18 inches, and it technically varies from person to person, as it was defined as the length of one’s forearm.
That said, the cubit, thumb, hand, and pace are all practical measurements using one’s body parts as a standard to work from.
