It has twelve faces, so it's called a dodecahedron--but it has a more specific name as well: decagonal prism.
Unlike the "regular dodecahedron" which has twelve regular pentagonal faces, this one has a decagon (10-sided polygon) on top and bottom, and ten quadrilaterals that join these two big faces together.
If we're talking about the nicest possible prism of the type you described (two regular decagons and ten squares), then I suppose it would work as a wheel. A little bumpy, but doable.

yes - some prisims can roll - but the more faces it has the better it will roll.
If it only has 3 for example - it would prove difficult - If it has three hundred - then the angles are much less acute and therefore closer to a spherical shape.

Dodecahedron has twelve regular pentagonal faces.
Can it roll? Depends how hard you shove it!
For loads of other dodecahedra try Wikipedia.

Dodecagonal and with enough force applied, yes they can roll.
