Let, the cube is made by 12 rods, we know that M.I. of each rod is ML2/2 ,

   now let, talking about face of a cube at 2D i.e. a square ,

    so its diagonal(or its length)= √2L

    for square. MI is = M(√2L)2/2

                            = 2ML2/2

                            = ML2 (IT IS FOR 4 ROD) SO IT CAN BE :

                             =3ML2(FOR 12 RODS)
