Problem with PolyhedronData["Dodecahedron","VertexCoordinates"]

PolyhedronData["Dodecahedron","VertexCoordinates"]

If I execute this expression on the Wolfram Programming Cloud I receive vertex coordinates like this:

Root[1 - 20 #1^2 + 80 #1^4 &, 3]

I’m not sure what to do with it. I couldn’t simplify or convert it to NumberForm. I’m probably doing something wrong.

To get the numerical value to any desired precision, use N:

In[2]:= N[Root[1 - 20 #1^2 + 80 #1^4 &, 3], 20]

Out[2]= 0.26286555605956680301

More information about Root objects is at http://reference.wolfram.com/language/ref/Root.html
