Praxis 5003 Practice Question
Which of the following units is most appropriate to use for measuring the length of a standard pencil?
Correct Answer: B
Rationale: Measuring the length of a standard pencil is best suited to centimeters, as this unit provides a practical scale for everyday objects. A typical pencil is around 18 centimeters long, making centimeters both precise and easy to visualize.
Millimeters (A) are too small for this measurement, as they would result in unnecessarily large numbers (e.g., 180 mm). Meters (C) are too large, as they are best for measuring larger distances and would yield a fractional value (e.g., 0.18 m). Finally, kilometers (D) are inappropriate for such a small length, as they are designed for measuring long distances, such as those between cities.
