Given that 1 foot = 12 inches and 3 feet = 1 yard, how many...

This is a unit-conversion problem involving yards, feet, and inches. First, convert yards to feet. Since 1 yard equals 3 feet, multiply: 2.5 × 3 = 7.5 feet. Next, convert feet to inches using the given conversion of 12 inches per foot. Multiply: 7.5 × 12 = 90 inches. Therefore, the correct answer is C. Option A (72 inches) represents only 6 feet. Option B (45 inches) results from converting yards directly to inches incorrectly. Option D (54 inches) represents 4.5 feet. On the NEX exam, multi-step measurement conversions are common, and accuracy depends on converting one unit at a time rather than skipping steps.
