The volumes of the original cube and the resulting wire must be the same.

The cube volume is its edge raised to third degree, (14 cm)

^{3}=14^{3}cm^{3}= 2744 cm^{3}.A volume of a cylinder is L*π*r

^{2}, where L is its length and r is its radious.Hence we get an equality: L*π*(0.84 cm)

^{2}=2744 cm^{3}.It should be solved for L.
