    What do you think? What are the sidelengths of the cross section?

    The 10 length along the bottom isn't really going to affect things. You can look at lengths which are parallel and the same length. The cross-section is 7x7

    The diagram doesn't actually indicate that the prism is perfectly bisected, so I wouldn't say you could label those as 5 and 5.

    That's a 50/50 split :-) So yes, as you can see the butter you get on the knife from cutting the butter stick is a 7 by 7 square

    At smooth math, I said IF it was. Otherwise it's this: |dw:1342813098005:dw|
