For the volume and surface area to be whole numbers, it is almost certain that all the dimensions of the box are whole numbers. So do some trial and error to find that x=4.
So the length and width of the square base are 4, and the height is 6.
You can confirm that those measurements make the surface area 112; but it is not necessary.

Bottom dimensions x and x.
height y.
, ;
and just those should be enough without using the surface area description .

One of the solutions is x=4.
This would make

check
6*4*4=96?
24*4=96
96
-
4^2+4*4*6=112?
16+4*24=112
16+96
112

Both conditions work.
