10
11
12
15

Explanation:

Step1: Identify operation

We need to divide the total number of valves by the number of boxes. So the operation is division, with the formula $\text{Valves per box}=\frac{\text{Total valves}}{\text{Number of boxes}}$.

Step2: Substitute values

Total valves = 144, number of boxes = 12. So $\text{Valves per box}=\frac{144}{12}=12$.

Answer:

12
