Final answer:
By converting 6 meters to 600 cm and dividing by the length of each piece, we can cut 300 pieces of 2.0 cm wire from a 6-meter roll of copper wire.
Step-by-step explanation:
To determine how many 2.0 cm pieces can be cut from a 6-meter roll of copper wire, we first need to ensure that the units of measurement for both the pieces and the total length of wire are the same. Since 1 meter is equal to 100 cm, we can convert 6 meters to 600 cm. Then we divide the total length of the wire by the length of each piece to find the number of pieces.
600 cm (total length in cm) ÷ 2.0 cm (length of each piece) = 300 pieces
Therefore, 300 pieces of 2.0 cm wire can be cut from a 6-meter roll of copper wire.
