Question: 1 / 400

Which metric unit is equivalent to 10 meters (m)?

Decimeter

Meter

Hectometer

Decameter

To determine which metric unit is equivalent to 10 meters, it’s essential to understand the metric system's prefixes and how they relate to the base unit of a meter.

A decameter is a metric unit that represents ten meters. The prefix "deca" means ten, so one decameter equals ten meters. Therefore, when the question asks for the metric unit equivalent to 10 meters, a decameter is the correct answer.

In contrast, a decimeter represents one-tenth of a meter, meaning it is much smaller than a meter. A hectometer is equivalent to 100 meters, which is greater than 10 meters. Lastly, a meter is the base unit itself, not an equivalent unit to 10 meters. Thus, understanding these metric prefixes clearly indicates that the decameter is the appropriate choice for a unit equivalent to 10 meters.
