(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

When the temperature of a metal cylinder is raised from 0.0°C to 100°C, its length increases by 0.23%. Find the percent change in density.

2. Relevant equations

∆L = L∆T

p=m/v

3. The attempt at a solution

I don't have any real idea how to start the problem. How do I relate the change in length to the change in volume? I know that mass is constant.

Thanks
