what is cubit? explain why cannot be used as standard unit of length ​

Answer 1

Answer:

✨Handspan and cubit cannot be used as a standard unit of length . This is because these are not particular measurements . ... This is because the distance between them is very large and milimeters are a very small unit of length . It can be measured in larger units of length like kilometers.

Answer 2

Answer:

Cubit is an ancient measure of length, approximately equal to the length of a forearm. It was typically about 18 inches or 44 cm, though there was a long cubit of about 21 inches or 52 cm.

As everyone's length of forearm can be different so it is not so relevent and thus not used as a standard unit.
