**1. The problem statement, all variables and given/known data**
Can someone please try to help me with this. I have a bcc structure and the question is ''Clearly indicate the unit translation vectors and state their value in Å.

I have attached the sketch :

are those t1,t2,t3 translation vectors?

I know the cell parameters are:$\displaystyle a=b=c=31652\AA$

Are these correct values of t1,t2,t3 then?

$\displaystyle t_{1}=(-\frac{a}{2},\frac{a}{2},\frac{a}{2})=(-15826,15826,15826)\AA ?$

and similarly the rest?

And one question more. We need to calculate the volume of the conventional unit cell and volume of the primitive unit cell, is this correct?

$\displaystyle V_{conv}=a^{3}=3171\AA^{3}$

$\displaystyle V_{primitive}=\frac{V_{conv}}{2}}=1585.5\AA^{3}$

Is the plane which has the highest degree of compaction (101)??

and the deree of compaction$\displaystyle \frac{\sqrt{2}}{a^2}}$???

Does latex work on this forum at all?
