In crystallography, the cubic crystal system is a crystal system where the unit cell is in the shape of a cube. This is one of the most common and simplest shapes found in crystals and minerals.

There are three main types of these crystals:

• Primitive cubic
• Body-centered cubic
• Face-centered cubic

Name	Description	Picture
Primitive cubic	One atom at each corner of the cube.
Body-centered cubic	One atom at each corner of the cube, and one in the middle of the cube.
Face-centered cubic	One atom at each corner of the cube, and one in the middle of each face (side) of the cube.
