$\text{17.1 cm}$

#### Explanation:

Your tool of choice here will be the conversion factor

$\textcolor{b l u e}{\underline{\textcolor{b l a c k}{\text{1 in = 2.54 cm}}}}$

In your case, you want to convert the number of inches to centimeters, so set up the conversion factor as

$\text{what you need"/"what you have" = "2.54 cm"/"1 in}$

This means that you have

$6.75 \textcolor{red}{\cancel{\textcolor{b l a c k}{\text{in"))) * "2.54 cm"/(1color(red)(cancel(color(black)("in")))) = color(darkgreen)(ul(color(black)("17.1 cm}}}}$

The answer is rounded to three sig figs, the number of sig figs you have for the number of inches.
