14 mL of oil is dispersed in water as spherical droplets of uniform radius 0.60 micrometre. The oil-water interfacial tension is 0.038 N/m. Neglecting the area of the original bulk oil, calculate the minimum work in joules needed to create the interface (two decimals). Use total area $=3V/r$ for spheres of total volume V.

Numerical answer type, answer in J, tolerance 0.02.
