For an ordered A$-$B metal alloy, answer the following questions $($Show your chosen

Bravais lattice and lattice parameters in the plot$).$ Assume that $r_A,$ the radius of $A$

atom $($open circles$)$ is $1\mathrm{.}3,r_B=1\mathrm{.}0($dark circles$),r_C=1\mathrm{.}5($red cross$-$hatched

circles$),A{W}_A($atomic mass$)=60\frac{g}{m}ol,A{W}_B=40\frac{g}{m}ol,A{W}_C=80\frac{g}{m}ol,$ and

$N_A=6\mathrm{.}022{10}^{23}$ atom$/$mole$.($The following cuboid has width $=$ length $$ height$)$

Density $($in $\frac{g}{c}{m}^3)$:$\_$

im struggling at finding the corect structure and a reasonable packing factor
