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.

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.
6 (SIX) rulers! One foot equals twelve inches!
None.
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

A standard flag's size can vary, but a common size is 3 feet by 5 feet. To convert this to inches, that's 36 inches by 60 inches. Therefore, the flag's area in square inches is 2,160 square inches. A 12-inch ruler has an area of 12 square inches when considering its length and width, so you would need approximately 180 12-inch rulers to cover the area of that flag.

The answer depends on the length of each ruler.
