    Using the given formula, replace sa with the given surface areas and solve for s:

    Surface area = 1200

    s = √1200/6

    s = √200

    s = 14.142

    Surface area = 768

    s = √768/6

    s = √128

    s = 11.313

    Difference:

    14.142 - 11.313 = 2.829 inches

    Round answer as needed.
