Yes, pyrite does form cubic crystals. Pyrite can form different types of crystals, including, cuboid crystals, raspberry-like framboids, T-shaped crystals, and dodecahedral crystals.
Pyrite has the property fracture. - Raymond Cheung
If you place an iron pyrite cube in mercury it will produce about a millivolt of current in water. More in salt water or vinegar or free radicals. This is a completely unexplored way to generate free electricity. It is not due to galvanization since the cube is the dependent aspect. Take the cube out and the amperage disappears (slowly but surely over time). This indicates both a capacitance and current generating characteristic that is unique to the interaction of the cube and mercury and the water provides the connective volt potential (although a different medium would yield better results.
Pyrite is FeS2, an iron sulfide.

Yes, Pyrite can conduct electricity.
Pyrite is the mineral whereas a pyrite 'cube' happens to be the habit in which the mineral has crystallised

A cube has only one shape and that is of a cube! It has six faces.
They're both shapes... and three dimensional shapes.
They are both 3-dimensional shapes.
There is only one cube shape and it is called a cube or a regular hexahedron.

No, a cube is a cube and a rectangular prism is a rectangular prism. They are two different shapes.
You can make many such shapes. One of them is the cube.
It is because they all are 3D shapes
