A bar made of a particular metallic alloy has a length of 10 cm at a temperature of 24 oC and a length of 10.015 cm at the boiling point of water.

(a) If a second bar made of the same material were 10 m at 24 oC, how much longer would this bar be at the boiling point of water?

The answer has to be in cm. So i converted 10m to cm, 1000 and then put on the .015. Ended up with 1000.015. and that's wrong. I need to find delta L. I know this is dealing with thermal expansion, but I need help figuring out how to do this.
