How many hand spans are in a cubit?

Why should we not measure the length with hand span?
The size of the foot and hand varies from person to person. If footsteps or hand span of two persons are used to measure the length respectively, then the two distances may not be equal. Thus, a footstep or hand span are not the constant quantities. Hence, they cannot be used as a standard unit of length.
