Final answer:
The electrician can cut the 6-foot copper wire into 18 pieces, each piece being 1/3 foot long.
Step-by-step explanation:
The electrician has 6 feet of copper wire and needs to cut it into pieces that are each 1/3 foot long. To find out how many pieces he can cut from the 6-foot wire, we divide the total length of the wire by the length of each piece.
Total pieces = Total length of wire / Length of each piece
Total pieces = 6 feet / (1/3 foot)
Total pieces = 6 * 3/1
Total pieces = 18
Therefore, the electrician can cut the wire into 18 pieces that are each 1/3 foot long.
