Can Molecular Distances Determine the Volume of Objects?

TL;DR Summary

Is there any calculation for distance between molecules to find out the volume of shapes around us?

Molecules give shape to everything around us,so I want to know is there anyway to find out volume of shape(like rock)by the distance between molecules?

If you know the number of atoms or molecules: Sure. Distances between them can be calculated. Sometimes there are multiple possible arrangements, then there will be multiple possible answers.

Ok if we consider avagadro number 6.02×10²³ for amount of our molecules then how we can calculate it?

No, the number of atoms in your object.

Toy example: Let's say your atoms form a simple cubic lattice with 0.4 nm separation. The volume per atom is just that length cubed. If you have 10¹⁸ atoms then you have 10¹⁸ times that volume. As an example they might form a cube with a side length of 1 million atoms, or 0.4 mm in each direction.
