Explanation:

Step1: Understand proportional relationship

The height \( h \) of DVD cases is proportional to the number of cases \( n \), so \( h = k \times n \), where \( k \) is the constant of proportionality (13 mm per case).

Step2: Calculate height for 12 cases

Substitute \( n = 12 \) and \( k = 13 \) into the formula: \( h = 13 \times 12 \)
\( h = 156 \)

Answer:

156
