Answer:

Step-by-step explanation:

volume of cuboid =  lbh

      =3x.2x.1x

volume = 10368

   10368=3x.2x.1x

             = 6x^3

   6x^3 = 10368

    x^3 = 10368/6

     x^3= 1728

     x = ∛1728

     x  = 12

    length = 12*3=36

    breadth = 12*3 = 24

     height = 12*1  = 12

 

       TSA of cuboid = 2(lb+bh+hl)

                               = 2(36*24+24*12+12*36)

                               =2(864+288+432)

                                =2*1584

                                = 3168

           money required to polish = 0.5*3168

                                                       =Rs1584

                            hope you understand
