1) The effective number of Cu atoms in a unit cell =

equals 8 cross times 1 over 8 plus 6 cross times 1 half equals space 1 space plus space 3 space equals space 4

2) The effective number of Ag atoms in a unit cell =

equals space 12 space cross times 1 fourth equals space 3

3) The effective number of Au atoms in a unit cell = 1

So, the general formula of the alloy is Cu₄Ag₃Au
