If a measurement is 3 feet 9 inches, how many inches is that?

Explanation:
Converting feet and inches to just inches is the key idea here. There are 12 inches in a foot, so 3 feet equals 3 × 12 = 36 inches. Add the extra 9 inches: 36 + 9 = 45 inches. So the measurement in inches is 45. For reference, 42 inches would be 3 feet 6 inches, 48 inches is 4 feet, and 50 inches is 4 feet 2 inches, which don’t match this measurement.
