    The answer to your question is: 3600 cm ²

    Step-by-step explanation:

    Rectangular box:

    length = 40 cm

    breadth = 25

    height = 20 cm

    Area =

    Area of the base = 40 x 25 = 1000 cm²

    Area of the lateral sides = 2 (40 x 20) = 1600 cm²

    Area of the sides = 2 (25 x 20) = 1000 cm²

    Total area = 1000 + 1600 + 1000 = 3600 cm²
