please show all work, I will rate.

Assume that 1.0 kg of cartridge brass (an FCC solid solution alloy comprised of 70 wt.% Cu-30 wt.% Zn) has been cold worked to achieve a dislocation density (perfect basis of 1.0(102) cm 2 Further assume that all these dislocations are separated into pairs of partial dislocations with stacking faults lying between the partials (ie, the partial dislocation density is 2.0(1012) cm2). Use Fig. 18.17 to assist you in estimating the total area (in cm?) of such stacking faults in 1.0 kg of cartridge brass. (hint: (1). The rule of mixtures applies to the lattice parameter in brass; (2) The shear modulus of cartridge brass is the same as the shear modulus of pure Cu; (3) The density of dislocation is measured by length per unit volume, e.g., cm/cm", which gives cm) 60 50 40 Stacking Fault Energy (m/m) 30 (at 30 wt. %Zn, the stocking fault energy is 14 m3/m?) 20 10 0 30 10 20 Zn Content (wt. %) Assume that 1.0 kg of cartridge brass (an FCC solid solution alloy comprised of 70 wt.% Cu-30 wt.% Zn) has been cold worked to achieve a dislocation density (perfect basis of 1.0(102) cm 2 Further assume that all these dislocations are separated into pairs of partial dislocations with stacking faults lying between the partials (ie, the partial dislocation density is 2.0(1012) cm2).
