Question: 1 / 400

What error did the student make in recording the length of a pencil if they wrote 8mm instead of the correct unit?

The unit of measure is incorrect. The student should have used centimeters instead of millimeters.

The correct answer identifies that the unit of measure is incorrect. The student wrote the length of the pencil as 8mm, but in this context, centimeters would be the appropriate unit, especially if the measurement is intended to convey a more practical understanding of the length.

Using millimeters can sometimes be appropriate for very small measurements, but pencils are generally measured in centimeters for clarity and common usage in everyday contexts. If the expectation is to express lengths that people commonly understand without the need for conversion, centimeters would typically be more effective.

The other responses suggest alternatives that do not align with standard practices for measuring such items or would lead to further confusion regarding proper metric usage. This highlights the importance of using the most suitable unit of measure in the context of the object being measured.
