  1. 8 * 10 = ?
    2(8 * 12) = ?
    2(10 * 12) = ?

    Add the three products together.

  2. For an open-top rectangular prism with width w, length L and height h,
    the area of the base is wL.
    The area of the 4 sides is
    2h(w+L)
    So the surface area of the open prism/bag is
    A=wL+2h(w+L).
    The correct answer is one of the given choices.
