CuZn

Brass is an alloy of copper and zinc. The 10 centimeter brass cube has a weight of 8.6 kg. Copper density is 8930 kg/m3, the zinc density is 7130 kg/m3. Calculate how many kg of copper and zinc a cube contains.

Correct answer:

m =  7.2928
z =  1.3072

Step-by-step explanation:


m+z = 8.6
m/8930+z/7130 = 0.1^3

m+z = 8.6
0.000112m+0.00014z = 0.001

m = 7.292833
z = 1.307167
