Homework Help: geometry

Posted by Anonymous on Thursday, April 28, 2011 at 8:53am.

The lateral area of a prism is 144cm^2 (lateral area is surface area without the bases). If the height is double the width, and the length is triple the width, what is the surface area?

I got the answer wrong; its supposed to be 196. Can anyone explain how to do the problem?
