Answer:
162 pieces
Step-by-step explanation:
a yard = 3 feets and a feet = 12 inches.
therefore a yard =3*12=36 inches
so,
18 yards = 36 inches *18 = 648 inches.
now, how many 4 inches pieces?
total pieces= total size of fabric divide by size of piece needed
therefore
total pieces=648/4 = 162 pieces.
