Here's the question you clicked on:

The prism shown below is sliced by a plane perpendicular to the base.
What statement best describes the cross section obtained? It is a square of side length 10 cm. It is a rectangle of length 10 cm and width 7 cm. It is a square of side length 7 cm. It is a rectangle of length 7 cm and width 5 cm.
What do you think? What are the sidelengths of the cross section?
@Smoothmath feel free to use my diagram to explain if she has more questions
@agentx5 , nice drawing.... must have taken a while...:)

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
It is a square of side length 10 cm. It is a rectangle of length 10 cm and width 7 cm. It is a square of side length 7 cm. It is a rectangle of length 7 cm and width 5 cm.
so its c right ?
woo thanks (:
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|
