A dimension on a plan reads 3 feet 6 inches. What is this length in inches?

Explanation:
Converting feet and inches to a single unit is the skill being tested here. Since 1 foot equals 12 inches, convert the feet portion and then add the remaining inches. For 3 feet 6 inches, multiply 3 by 12 to get 36 inches, then add the extra 6 inches: 36 + 6 = 42 inches. So the length in inches is 42. The other numbers don’t fit because 36 would drop the extra 6 inches, 48 would be 4 feet, and 54 would be 4 feet 6 inches.
