Six. There are three feet in one yard.
12 of them.
These many.
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
it should be 27. there are 3 feet in a yard and 3 times 9 equals 27.
