Pretty Basic Function Word Problems..

http://img213.imageshack.us/img213/7976/img0589v.jpg

For this first one I tried to find a formula that I could relate to volume and surface area. Needless to say I didn't get very far..

I pretty much got stuck at the Surface Area Formula for rectangles: 2lw + 2lh + 2wh.

Help would be awesome.

I was pretty unsure of where to start for this one. I tried some stuff but got nowhere.

I'd really appreciate a helping hand, I have my first test coming up and I can't grasp this stuff.

Word problems have always been my Achilles heel.
