Answer 2

Answer:

The weight of 6 meters of copper wire is 3kg.

Step-by-step explanation:

In the question here we have been mentioned that 20 meters of the uniform copper wire have a weight of about 10 kg. We here need to calculate the weight of 6 meters of the wire. We will take into account the use of the unitary method for this. We have as follows;

Weight of 20 m of copper wire = 10 kg

∴ Weight of 1 m of copper wire = 10 kg ÷ 20 = 0.5 kg

∴ Weight of 6 m of copper wire = 0.5 kg × 6 = 3 kg

Hence we have the weight of 6 meters of copper wire is 3 kg.
