In order to find the length of wire, we need to find the volume of cube and compare that to the dimensions of the cylinder as both their volumes are equal.
So volume of cube = a³
= 4 x 4 x 4
= 64 cm³

Now, volume of a cylinder = πr²h
= 22/7 x 0.1 x 0.1 x h = 64
= 0.22h/7 = 64
= 0.22h = 448
= h = 448/0.22 = 2036.36 cm
So length of wire = 20.3636 m

Hope that helps !!

volume of cube=volume of cylinder
volume of cube=a^3= 4 x 4 x 4

= 64 cm³
radious of cylinder=1/10 cm
Now, volume of a cylinder = πr²h
                     = 22/7 x 1/10 x 1/10 x h = 64
                     22h/700 = 64
                     22h= 44800
                     h = 44800/22
                     = 2036.36 cm
to convert cm into m multiply with 100
And length of wire = 20.3636 m
