**Unit Cell -- Linear Density -- BCC&FCC**

## Homework Statement

Calculate the linear density for the most densely packed directions in BCC and FCC. Note the difference in linear density. Note the difference in linear density.

## Homework Equations

LD = #of atoms/length

## The Attempt at a Solution

I arrive at an answer, however my answers for BCC and FCC are the same. I chose vector [110] for the BCC and got this for the LD equation: LD = 2/4R

For FCC I chose vector [101] ... LD = 2/4R

I was hoping someone could see my error.
