Question

a metal cryistallises in two cubic phases fcc and bcc whose unit cell edge lengths are 2A° and 4A° respectively.the ratio of densities of fcc and bcc are? plse give me the step too​

Answer 1

Answer:

A metal crystallizes into two cubic phases, face-centred cubic and body-centred cubic, which have unit cell lengths

and

, respectively. Calculate the ration of densities of fcc and bcc.
