Final answer:
The grass height of 5.08x10⁻⁵ miles is most appropriately measured in inches, resulting in approximately 0.323 inches when converted.
Step-by-step explanation:
The grass in the outfield of a professional baseball stadium is trimmed to a height of 5.08×10⁻⁵ miles. The most appropriate unit of measurement for such a small height would be inches. Miles are too large a unit for measuring such small dimensions, and converting this measurement to inches would provide a practical and relatable unit. Although not explicitly stated in the problem, using the conversion that 1 mile equals 63,360 inches, the height in inches is approximately 0.323 inches (5.08×10⁻⁵ miles × 63,360 inches/mile). This is a practical and understandable height measurement in day-to-day terms.
