    Answer:

    given side of a cube, a = 2cm

    then, l = 4cm

    b=2cm

    h=2cm

    total surface area of the cuboid= 2(lb+bh+lh)

                                                        = 2(4×2+2×2+42)

                                                        =2(8+4+8)

                                                        = 2×20

                                                       =40cm²
