Crystal structures.?

Lithium bromide crystallizes with a NaCl type structure. What is the total number of ions (positive and negative) in the unit cell?
I have 8... but I'm not sure... any help would be great. Thanks!

In lithium bromide structure the space lattice is face centered cubic.
Each ion has 6 ( not 8 ) neighbors of the opposite kind and is bound to these 6 ions which are arranged at the corners of the octahedron
