Early civilization used a cubit as a unit of measure. Acubit is the length from the middle finger to the elbow. Estimate the average height

Here's the link:  https://en.wikipedia.org/wiki/Cubit

If we consider the cubit to be about 15 in....then... 4 of them would be about 60 in....and this is about the height of the average man (more or less)

Does that help???

According to Wikipedia......the cubit ranged from about 15 to 20.4 inches in length......if we consider the average man to be about 6 feet tall (60 in).....then  60/15  = about 4 cubits

If a quadrateral has exactly one pair of sides parallel it must be a:

A.trapezoid

B.rhombus

C.parallelogram

D.rectangle 

Phil Can you please go into detail how you got the cubit information ? 15 - 20.4 inches

Can you rexplain how you got the answer , Thank you
