  1. Step-by-step explanation:

    according to the box it has 6 faces, which means he used 6 different colours

    so the area can be represented by

    l×h for the first face

    l×h for its opposite face

    b×h for the second face

    b×h for its opposite face

    l×b for the third face

    l×b for its opposite face

    Now we have,

    l×h+l×h+b×h+b×h+l×b+l×b

    =2(lh+bh+lb)
