You are given N volumes of a substance.

What is the most aerodynamic shape you can create with it?

What is the least?

I would think a one atom thick straight line would be the most aerodynamic

And a one atom thick disc would be the most

long needle

planar surface normal to movement direction, or sphere if you allow it to rotate

Just a guess.

Maybe an irregular edged disk to create more disturbances and wind drag?

Wouldn't a point with as many radial spines as possible create more drag due to a much larger surface area?

orient them in a way that minimizes/maximizes surface area orthogonal to the direction of the airflow

Or a hollow ball, since it can have a larger diameter. I did say it was just a guess.

The important thing from my perspective is the projected surface area rather than the total surface area, so a fractal surface may not give you a whole lot.
