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.

There is no one answer, as there is no one size for a flag. Tell us the size of the flag in question, and we can answer it.
6 (SIX) rulers! One foot equals twelve inches!
You need to cut a 9 foot piece of plywood into 12 inch sections. Every cut also removes 1/8 inch. How many 12 inch sections can you get out of the 9 foot piece of plywood?

Estimate how many 12 incj rulers will be about the same length as the object

It depends on how long the ruler is, but most rulers are 12 inches and 12 inches=1 foot...so the answer would be 4 rulers for 4 feet...thats a lot of fours :) I am presuming you are using 12inch rulers so as there are 12inches in a foot you will need 4 rulers

The answer depends on the length of each ruler.

joking, right?

It depends on the size of the door. Length times the Width.
