1. The problem statement, all variables and given/known data Find the volume: Prism formed by x+z=1, x-z=1, y=2, y=-2, and the yz-plane. 2. Relevant equations 3. The attempt at a solution Okay, so I sketched the drawing and I found that I could take the upper region of the xy-plane with respects to x and z and a triangle was formed. The bounds were from 0 to 1 with respects to x and from 0 to z=1-x with respects to z. So i integrated dzdx and got the answer of 1/2 for the triangle. I then multiplied the triangle area by 2, since we have to take the volume of above the xy-plane and below the xy-plane which due to symmetry, I assume this works. I then multiplied by 4 as y=-2 and y=2 distance results in 4 units. So my answer came to be "4". This seems a bit too...easy, however, I can't find anything conceptually wrong with my procedure. Did I perform this operation correct?
