Need help with practice problem

(0) Suppose that a solid occupies the region: E = {(x,y,z) : 35+ 2 31, z 2 0, x 2 yz} in R3. Furthermore, suppose that the solid has variable density given by the function p(x, y, z) = x + 2. Set up but do not evaluate an iterated integral with differentials in the order: dxdydz that will yield the mass of the solid
