I'm stuck on a moments of inertia question. Any advice on how I could solve this? (A) Find the moment of inertia of a square box of sides 2l and mass m at a vertex (8/3ml²) which is perpendicular to the phase of the plane given that 4 rods of length 2l and mass m are touching the box at each of the sides. (B) Find the…

(B) Find the period of oscillation at the vertex.
