If 9 thickness measurements are taken at each end of a 12-inch beam segment, how many total measurements are recorded?

When measurements are taken at both ends, you add the counts from each end. There are 9 thickness measurements at one end and 9 at the other, so you sum them: 9 + 9 = 18. Since two ends are involved, the total is 18 measurements recorded.
