Problem
A particle-level model of steel shows a cluster made up of eight contiguous body-centered cubic (bcc) unit cells of iron arranged two unit cells along each axis. Four carbon atoms are drawn in octahedral holes located completely inside the cluster. Based on this model, what is the approximate atom percent of carbon in the represented portion of steel?
(a) 11 \%
(b) 5 \%
(c) 20 \%
(d) 33 \%
