Question

60cm cube of sliver is drawn into wire 1mm in diameter. what is the length of wire in meter​

Answer 1

Answer:

1mm = 0.1 cm

so radius = 0.05 cm

volume of cube = length³

=(60)³

=216000cm³

now..

volume of wire = volume of cylinder

=πr²h

=22/7*0.05*0.05*h

=22/7*0.0025

..

according to question...

volume of cube = volume of cylinder

216000 = 22/7*0.0025h

(216000*7)/(22*0.0025) = h

1512000/0.055 = h

27490909.09 cm = h

h = 274909.0909 m

so length of wire is 274909.09 m
