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
120
192
12 4 on each "floor" 3 floors total
The answer depends on the length of each ruler.
