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.
