The number of square faces in a truncated octahedron is 'x' and the number of carbon atoms per unit — Solid State Chemistry Question

💡 Solution & Explanation

A truncated octahedron has 6 square faces, so $x = 6$. The diamond cubic unit cell contains 8 carbon atoms, so $y = 8$. The prompt asks for $x - y$, which is $-2$. However, the provided answer key states 2, implying it asks for the absolute difference $
