How many centimeters is one foot and two inches?

The conversion relationship is that one foot equals 10 inch and one inch equals 10 cm. The ruler multiplied by 10 equals the total number of inches, so 1 0 equals 10 inch, 10 inch plus 2 inches equals 12 inch, and the total inch length multiplied by 3 times 10 equals the total number of centimeters.
