Answer:
Please see the attached picture for reference.
The volume of a rectangular object is defined as
Volume = base*height*width
In the picture below, we can see that the base is denoted as x , the height is denoted as y and the width is denoted as z
Volume = x*y*z
96 = x*y*z
Since there is no more information on the problem, we can find the height of the box in terms of the other two variables (width and base)
y = 96/(x*z)
height = Volume/(base*width)
