This is how i did the mass integral

Homework Statement A solid metal rod with dimensions 5 x 2 x 1 is placed with one corner at the origin, such that 0≤x≤5, 0≤y≤2 and 0≤z≤1. The rods density is described by ρ(x) = (3x2 +10x) / 25 a) find the total mass of the rod b) find the x-coordinate of the centre of mass of the rod. Homework...
