A box is
in. long, and
in. wide. What is the longest poster you could fit in the box? Use pencil and paper. Explain why you can only fit one maximum-length poster in the box but you can fit multiple
posters in the same box.
This question is formated weirdly but the dimensions of the box are 12 by 20 by 8 inches on each side. The longest poster you can fit in the box is 20 in. You can't fit 23 in posters in the box so I don't understand the second part of the question.
Hope it helps!
