Suppose you have taken a dilute solution of oleic acid in such a way that its concentration becomes $0 . 01{cm}^{3}$ of oleic acid per ${cm}^{3}$ of the solution. Then you make a thin film of this solution (monomolecular thickness) of area $4{cm}^{2}$ by considering $100$ spherical drops of radius \left(\dfrac{3}{40\pi}\right)\dfrac{1}{3} \times {10}^{- 3}cm .$Then the thickness of oleic acid layer will be$x \times {10}^{- 14}m$. Where$x is ________ .
