volume integral over a cube

[sammw]

I'm trying to solve this: integ. ((x/a)+ (y^3/a^3))*(xi+yj+zk)dx dy dz for a cube -a to a and i keep getting the wrong result. i'm having trouble with understanding the vector part in it. how does it affect the volume integral? what's the direction of the result?
thanks
