GPT 3.5
To find the length of the metal rod in centimeters, we divide its length in inches by the conversion factor between inches and centimeters, which is 2.54 cm/inch.
So, the length in centimeters is 21 inches × 2.54 cm/inch = 53.34 cm.
Rounding this result to the nearest centimeter gives a length of 53 centimeters.
So, the length in centimeters is 21 inches × 2.54 cm/inch = 53.34 cm.
Rounding this result to the nearest centimeter gives a length of 53 centimeters.
