A manufacturer wants to produce crude benzene models for the chemistry department. The manufacturer plans to do this by punching regular hexagons out of steel; such that edge length and thickness are in ratio

1000 : 1 .

Steel ruptures at shear stress greater than

4 \times 10^{8} N m^{- 2} .

If total shearing force applied is

6 \times 10^{5} N,

then find maximum value of thickness of the hexagonal plane (in
