1. The problem statement, all variables and given/known data Compute the volume of the solid bounded by the four surfaces x+z=1,x+z=−1,z=1−y2,z=y2−1 2. Relevant equations Fubini's theorem? 3. The attempt at a solution I have tried to visualize this solid and define the limits; when I attempted to integrate by dxdzdy (in that order), I set the limits for the first integral as -z-1 to -z+1, the second integral as y^2-1 to 1-y^2, and third integral as -1 to 1, but the I'm not getting a value due to the second integral evaluating as zero. I feel almost certain that the problem mainly has to do with defining the correct limits and order of integration, but I'm having a bit of trouble here. Thanks.
