    Does the question state if the box is open or closed?

    i tried doing 6 x 11 x 8 = and got 529

    Hmm well for now then we can assume that it's open

    Well let's take this one step at a time. Imagine the bottom is just a 2-D rectangle

    The dimensions would be 11 and 8, for an individual surface area of 88, we'll remember that. Since we're assuming the box is open, we'll leave it at that

    Now the sides, 8 by 6. This gives a surface area of 48 inches^2----- times two because there are two of those surfaces

    Finally 6 times 11 is 66, times 2 is 132

    Adding all of these components together we get 316 in^2

    @RunawayGalaxy I'm pretty sure it'd be a closed box. Not enough information otherwise because you don't know which side would be open, and I don't think there's an answer choice for any of those options.

    Assume it's closed.

    I was just going to solve for open, and then add the top and see if one of those answers was missing

    Which I just did, and the open top answer is not there, so the box has to be closed

    So moazzam, I'll leave the rest to you, just add the 88 to 316 and multiply by your cost

    404 but whats the cost?

    9c

    Yes, because you are being charged 9c per square inch, and we just found the surface area of the box in square inches
