For the volume of the unit cell volume, we will choose the appropriate number of atoms. The equation (1) represents the conversion of coordinates from the fractional coordinate (V ⃑) is cartesian coordinates (V ̂)
For determining the volume of the unit cell volume, we will select a suitable number of atoms equation (1) represents the coordinate transformation from fractional coordinate (V ⃑) is cartesian coordinates (V).
For the unit cell volume, we choose an appropriate number of atoms with volume equation (1) represents the transformation from the fractional. Coordinate (V ⃑) is a Cartesian coordinates (V ̂).
