How many yards in 4x37'x37'?

Answer 1

Apart from the fact that there is no indication as to whether the 4 refers to 4 inches, 4 feet , 4 yards, 4 miles or even 4 light years, the question cannot be answered sensibly.

A yard is a measure of length whereas 4*37'*37' is either a measure of area (if the 4 refers to 4 lots of) or to a measure of volume (if there is some unknown units of length associated with it). In either case, the two measure different things and, according to the very basic principles of dimensional analysis, conversion from one to the other is not valid.
