A box is
12
in. high,
20
in. long, and
8
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
23-in.
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!
