A box is cuboid with dimensions 26 cm by 15 cm by 20 cm all measured to the nearest centimeter . Disc cases are cuboids which measure 1.6 cm by 14.2 cm by 19.3 cm .all measured to the nearest millimeter .if the disc cases are stacked as shown show that it may not be possible for 16 cases to fill in the boxs

So, work out the volume of the cuboid, and the volume of a disc case and then you would take the volume of 16 disc cases from the total volume of the box and in this case you should still have volume left greater than that of 1 disk case - which you will if you do the question correctly

Before calculating the total volumes, think about how the dics cases would be arranged in the box (you didn't include the figure).
There's really only one way to do it and only one dimension you actually need to consider.
For that dimension, what is the maximum disc case length and the minimum box size. In that case, would it be able to fit 16 in there.

It is a year old, but If you're interested, think about how the box and case dimensions match. Then it should just be a simple division.
