Find the surface areas of each plane
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
and then multipyed 529 by 0.09
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.
$18.18 $27.72 $36.36 $45.54
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?
Yes, because you are being charged 9c per square inch, and we just found the surface area of the box in square inches
Ok and i got C correct rigth?
