How many 12-inch rulers will be the same length as a door?

Oh, dude, it's like basic math time! So, a standard door is usually around 80 inches tall, right? So, if you divide that by 12 (the length of a ruler), you get about 6.67 rulers. But, like, since you can't have a fraction of a ruler, you'd need 7 rulers to match the length of a door. Math, man, it's wild.
