Explanation:
Your tool of choice here will be the conversion factor
#color(blue)(ul(color(black)("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
#"what you need"/"what you have" = "2.54 cm"/"1 in"#
This means that you have
#6.75 color(red)(cancel(color(black)("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.
