An inverse relationship can be represented two ways in an equation.
1) the two variables are multipled by each other on the same side of the equation.
2)the variables are on opposite sides of the fraction bar if on opposite sides of the equation
answer C shows this.

C
Varying inversely means that as one (in this case the cube of the width) increases, the other (length) will decrease. A, B and D show cases where as w^3 increases, L will also increase.
Another piece of information to be noted is that A and D are equal (divide both sides of D by k), and so can not be the correct answer.

c...Varies inversely means that the width must be in the denominator of a fraction in the equation. A constant value, k, would be in the numerator.
