| Question | Answer |
| square metre | The square metre or square meter is the SI derived unit of area with symbol m2 |
| Adding and subtracting SI prefixes creates multiples and submultiples; however, as the unit is exponentiated, the quantities grow geometrically by the corresponding power of 10. | For example, 1 kilometre is 103 (one thousand) times the length of 1 metre, but 1 square kilometre is (10^3)^2 (10^6, one million) times the area of 1 square metre, and 1 cubic kilometre is (10^3)^3 (10^9, one billion) cubic metres. |
