    Expert Answer:

    From the figure we have

    Height (h1) of larger cylinder = 220cm

    Radius (r1) of larger cylinder = = 12cm

    Height (h2) of smaller cylinder = 60cm

    Radius (r2) of smaller cylinder = 8cm

    Mass of 1 cm3 iron = 8 gm

    Mass of 111532.8 cm3 iron = 111532.8 x 8

    = 892262.4 gm = 892.262 kg
