Final answer:
The expression that represents the height of the box is f(x) / ((x + 6)(x + 2)).
Step-by-step explanation:
The volume of a rectangular prism is determined by multiplying the length, width, and height of the box. In this case, the length is represented by (x + 6) and the width is represented by (x + 2). To find the height, we can divide the volume function f(x) by the product of the length and width.
So, the expression that represents the height of the box is:
Height = f(x) / ((x + 6)(x + 2))
