Answer:
See Below
Step-by-step explanation:
To get volume of cuboid, we multiply the 3 dimensions.
<u>Volume of Box</u> = 28 * 15 * 20 = 8400
<u>Volume of 1 disc case</u> = 1.5 * 14.2 * 19 = 404.7
<u>Volume of 17 disc cases</u> = 17 * 404.7 = 6879.9
Since, volume of 17 disc cases is less than volume of the cuboid box, definitely 17 disc cases will fit the box.
This only got my 2 out of 4 marks but I hope it is still helpful and you can work on it.
<u>27.5×14.5×19.5 </u>= 7775.625cm³
<u>1.55×14.25×19.35</u> = 427.393125cm³
7775.625÷427.393121 = 18.19314495
This is about upper and lower bound so anybody please carry on and help me here is a start the part underlined is where I got the marks

3(2)-2(1-2) / 3-2
6-2(-1) / 1
6 + 2 / 1
8 / 1
= 8
