1 cubic nm = 1 nm^3 = 1e^27 m^3 1 mm= 1e3 m and 1 mm^3 (cubic mm) = 1e9 m^3

volume of a sphere is \[\huge \frac{4}{3}\pi r^3 \] diameter is 3.5, implying that radius is 1.75, substitute and u have a value in mm^3, then convert to nm^3

so I would do: \[\frac{4}{3} \pi (3.5)^3 \cdot 10^{9} m^3\cdot \frac{1 nm^3}{10^{27} m^3}\]
