    Step-by-step explanation:

    Let the Side of both cube be ‘a’

    lenght of the cuboid =2a

    breadth of the cuboid=2a

    height of the cuboid =a

    lateral surface area=2(l+b)×h

    =2(2a+2a)×a

    =2×4a²=8a²

    Tsa= 2(lb+bh+lh)

    = 2(2a×2a+2a×a+2a×a)

    = 2(4a²+2a²+2a²)

    = 2×8a² = 16a²
