Matching two rasters for cut/fill

Discussion created by kbarrek on Nov 29, 2012
I have two rasters that I plan to use for Cut/Fill function.  The two rasters don't quite match exactly which I understand they must for the Cut/Fill to work.  They align properly but because they were generated using different inputs, one is slightly larger in area. 

What can I do to get the two rasters to match for the Cut/Fill function?  I tried setting the MASK in the processing environments, but that didnt' give me the result I need.

Any help would be greatly appreciated.
