1. The problem statement, all variables and given/known data 2. Relevant equations triple integrals, center of mass 3. The attempt at a solution I set up the triple integral x: lower limit 0 upper limit 1 y: lower limit 0 upper limit 2 z: lower limit 0 upper limit 1 ∫∫∫ δ(x,y,z) dx dy dz => applied the limits for x, y and z, and δ(x,y,z) = 2 +xy -2z (given) I got mass is equal to 1. Then I tiried to find x bar (x coordinate of center of mass) set up this way: ∫∫∫ (x * δ(x,y,z) dx) dz dy divide by Mass (Mass = 1 from previous result) and got x bar = 1.667, which does not make sense, cuz 0≤ x ≤1 how come it is outside the x limits, or what was the mistake?
