Question 447926
Something is wrong because 5 cubic centimeters of wax is not enough
to make a crayon 8 cm long with 1 centimeter diameter, for it would
take at least 6.3 cubic centimeters to make one without the conical
tip. The conical tip would require even more wax.  Read the problem 
again and post again, for surely the 5 cm was a typo.
