What is bigger 100 inches or 3 yards and 1 foot?

To compare the two measurements, we first convert 3 yards and 1 foot to inches. Since 1 yard equals 36 inches, 3 yards equals 108 inches, and adding 1 foot (12 inches) gives a total of 120 inches. Therefore, 120 inches is greater than 100 inches. Thus, 3 yards and 1 foot is bigger than 100 inches.
