A 19.0 cm piece of copper pipe has a mass of 48.40g. What is the length of pipe if it has a mass of 170kg?

Answer 1

66.74 cm of pipe.

There are two different ways to do this, either find the cm/g or set up equal fractions and solve.

1. cm/g method

19cm/48.4g = 0,39256 cm per gram

0.39256 cm X 170 g = 66.74 cm of pipe.

2.equal fractions

19cm/48.4g=Xcm/170g

48.4X=3230

X= 66.74 cm
