**Simple Resistance Problem...help!**

## Homework Statement

A wire has a resistance of 0.008 W. What will the wire's resistance be if it is stretched to seven times its original length without changing the volume of the wire? (Give answer in W.)

## Homework Equations

R = Ch in V / I

## The Attempt at a Solution

I thought I would just multiply 0.008 by 7? But that's not right...I know this must be so easy but for some reason I am stuck!
