Which prefix represents 10^3?

Explanation:
In this topic, prefixes in the metric system encode powers of ten. The prefix that means a thousand is kilo, or 10^3. That’s why kilo is the right answer: it represents 10^3, as seen in examples like kilometer (1000 meters) and kilogram (1000 grams). The other prefixes represent larger powers of ten—mega is 10^6, giga is 10^9, and tera is 10^12—so they describe quantities far bigger than 10^3. Remembering that kilo stands for a thousand helps you identify the correct prefix quickly whenever you see a scale like 10^3.
