Re: Cardboard

MoyMarian, can you please keep all your questions in one post/thread? Otherwise, it looks as if you are spamming. Keeping all your posts in one place also makes it easier for you to find them later on.

Alos, if this is a homework question, you should do it yourself, or show us that you have made an effort to do it yourself. Asking someone else to do your homework for you won’t help you learn anything.

And before JurassicPlank1 comes to do this homework question for you, may I point out that JurassicPlank1’s solution to this problem

http://www.mathisfunforum.com/viewtopic.php?id=11551

is incorrect.

I suggest you do your own homework instead of copying somebody else’s mistakes.
