1. ## Multiple integral

Need helping starting this problem find the volume bound by $x+2z=4$ and $2y+z=2$ in the postive octant.

Will this be a triangle based pyramid?

2. I think it will be a square based pyramid, which mean it's volume is uniquely determined by it's base area and it's height.

$V=\frac{1}{3}Ah$.

3. I need to gat the answer by using integration.
