no idea. There must be some other information here. If you know the height and the width, the length can be anything unless you also know the volume or area or a diagonal.
I need the length to figure out the volume, I think I found it, I was just lookng for somebody to verify if I was correct.

SO PLEASE DON'T ANSWER THE QUESTION IF YOU HAVE NO IDEA, THIS IS THE SECOND TIME I HAVE POSTED A QUESTION WITH ALL THE FACTS, TRYING TO VERIFY IF I WAS ON THE RIGHT TRACK AND BOTH TIMES YOU SAID YOU DID NOT KNOW. ITS A WASTE OF MY TIME AND YOURS!

THANK YOU
AS A MATTER OF FACT IS YOU SEE MY NAME, POSTED WITH A QUESTION. DON'T ANSWER, AS YOU OBVIOUSLY DON'T KNOW THE ANSWER!
