1. Convert yards to feet:

* There are 3 feet in every yard, so 6 yards is equal to 6 * 3 = 18 feet.

2. Divide the total feet by the length of each piece:

* 18 feet / 4 feet/piece = 4.5 pieces

Answer: There are 4.5 four-foot pieces in 6 yards. Since you can't have half a piece, you can get 4 complete pieces with some leftover.
