<PRE><B>Question 460681</B>
A person wants to board a plane with a 5ft. long steel rod, but airline 
regulations say that the maximum length of any object or parcel permitted to be checked on board is 4ft.
 Without bending or cutting the rod or altering it in anyway, how did the person
 check it through without violating the rule?
:
Find a shallow box that has 4 ft square base. find the diagonal of the base
d = {{{sqrt(4^2+4^2)}}}
d = {{{sqrt(32)}}}
d = 5.7 ft, the 5 ft rod will easily fit in the box
