    Help with some very quick math homework?

    Would you end up with the same result if you computed the total surface area using the formula S = LA + 2B? Explain.

    EDIT: Wait a sec, let me ask my friend again to double check.

    ? That's an odd problem. Is it referring to a part of something else?

    Total surface area of what?

    Okay, here is what my friend said.

    "The instructions were:
    I told you the chart information I put?
    I said the front and back was 570 centimeters. Top and bottom was 114. Left and right box was 180 centimeters.
    114 centimeters as well.
    Well I was supposed to measure the length and width of a cereal piece.
    And that's what I did.

    I was supposed to measure the length and width of a cereal box.
    Well cereal box pieces,"

    So have you already calculated the surface area of something?

    I didn't calculate it, but my friend tried to.

    " 30 1/2 times 19 1/2 is 570. 6 times 19 1/2 is 114. 10 1/2 times 6 is 180 all of this times 2.
    Equals 1,728"

    She says she almost multiplied, I don't quite understand.

    " I multiplied something instead of added.
    If she needs to know 2B is the 2 bases of the cereal box. LA is the Lateral part."
