A metal crystallizes in 2 cubic phases foc and boc whose unit cell lengths are

3.5 \mathop {\text{A}}\limits^{\text{o}}

and

3.0 \mathop {\text{A}}\limits^{\text{o}}

respectively. The ratio of their densities is

View answer and explanation

Correct option: C

1.26

Option C (1.26) is correct because it accurately calculates the ratio of densities for FCC and BCC structures using their respective unit cell lengths and number of atoms per unit cell.
