1. The problem statement, all variables and given/known data Find the mass and the center of mass of the solid E with the given density function ρ(x,y,z). E is bounded by the parabolic cylinder z = 1 – y2 and the planes x + 4z = 4, x=0, and z=0; ρ(x,y,z) =6. m=? x=? y=? z=? 2. Relevant equations z = 1 – y2 and the planes x + 4z = 4, x=0, and z=0; ρ(x,y,z) = 6. 3. The attempt at a solution I got m = 96/5 but I'm not sure how to figure out x,y and z.
