two differences between tetrahedral void and octahedral void?

Following are the differences between tetrahedral voids and octahedral voids  

 Tetrahedral voidsOctahedral Voids
A void surrounded by 4 spheres is called a tetrahedral void.A void surrounded by 6 spheres is called an octahedral void.
In a solid,

Number of tetrahedral voids = 2 × Number of close-packed particles

In a solid, 

Number of octahedral voids = Number of close-packed particles


Figure 1 represents a tetrahedral void and figure 2 represents an octahedral void.
