I know how to put a sphere inside a dodecahedron but instead of a sphere I would like it to be another dodecahedron. How can I do it?

Graphics3D[{{Opacity[.3], FaceForm[Yellow], 
   PolyhedronData["Dodecahedron", "Faces"]}, Brown, Sphere[{0, 0, 0}],
   Boxed -> False}]

enter image description here

Kuba has identified the missing piece of the puzzle in his comment, Scale. With Scale you can make the dodecahedron smaller or larger. Other than that it's just a matter of replacing Sphere.

Graphics3D[{{Opacity[.3], FaceForm[Yellow], 
   PolyhedronData["Dodecahedron", "Faces"]}, Brown, 
  Scale[PolyhedronData["Dodecahedron", "Faces"], 0.5]},Boxed -> False]


Note where I placed Boxed. You include Boxed -> False but because its position is wrong it doesn't actually do anything in your example.


I personally tend to avoid using things like Scale[] when applying transformations to primitives. Instead, I just apply TransformationFunction[] objects directly to primitives, one way or another. As an example,

dod = PolyhedronData["Dodecahedron", "GraphicsComplex"];
ir = PolyhedronData["Dodecahedron", "Inradius"];
sc = ScalingTransform[RootReduce[ir/PolyhedronData["Dodecahedron", "Circumradius"]]
                      {1, 1, 1}];

Graphics3D[{{Opacity[0.4, Yellow], dod}, {Opacity[0.6, LightBlue], Sphere[{0, 0, 0}, ir]},
            {Green, MapAt[sc, dod, 1]}}, Boxed -> False]

inscribed dodecahedron

Graphics3D[{EdgeForm[GrayLevel[0, 1]], {Opacity[0.3, Orange], dod},
            {Yellow, MapAt[sc, dod, 1]}}, Boxed -> False]

two dodecahedra
