Answer 1

Answer:

1) find volume of the drilled copper wire.

2)for finding vol. of drilled copper wire you have to subtract the total vol. of wire -tolal vol. of aluminum filled.

3) then you will get the adject vol. of copper wire.

4)then, finally divide the vol.of copper wire/vol.of aluminum filled.

5)thus, you will get answer.
