In order to find the length of wire, we need to find the 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*4*4
= 64 cm3
Now, volume of the cylinder = 22/7*0.1*0.1*h=64
= 0.22h/7 = 64
= 0.22h = 448
= h = 448/0.22 = 2036.36 cm
So, length of the wire is 20.3636 m
