The volume of a packing box is 5 - x cubic feet. The width of the box is x feet and the length is x - 2 feet. The height is given by the expression Which of these values of x make the expression undefined?

By definition we have that the volume is given by

V = h * w * l

where

V: Volume

h: height

w: width

l: length

Clearing the height we have:

h = V / (w * l)

h = (5 - x) / ((x) * (x - 2))

The expression is not defined for the values of x that make the denominator zero:

((x) * (x - 2)) = 0

x = 0

x = 2

Answer

h = (5 - x) / ((x) * (x - 2))

x = 0

x = 2
