    Length of cube =a

    a3=64

    ⇒a=4

    Length of cuboid = 8=l

    breadth of cuboid = 4=b

    height of cuboid = 4=h

    Surface area =2(lb+bh+lh)

    =2((8×4)+(4×4)+(8×4))

    =2(32+16+32)

    =160 cm2

    Given,


    Volume of each cube = 64cm^3







    length of the cuboid =4+4= 8cm

    Breadth of the cuboid =4 cm

    Height of the cuboid = 4 cm

    T.S.A of cuboid =2(lb+bh+hl)

    =2(8×4+4×4+4×8)

    =2(32+16+32)

    =2(80)
