Hi!

The surface area wouldn´t affect at all in vacuum, but it will in air.

I can´t imagine that it would not affect in a liquid.

Think of it this way. Using newtons law F=ma

we know that a=acceleration is the derivative of v`(t) where t=time

so m*v`= mg - kv^2 This is usually presented in high school books as a differential equation for free fall with air resistance.

Where k is a constant, and this constant will include surface, shape etc.

v^2 is simply the speed squared.

Hope I helped somewhat, I am new at this myself.
