A cubic solid is made by atoms A forming close pack arrangement, B occupying one. Fourth of tetrahedral void and C occupying half of the octahedral voids. What is the formula of compound

Explanation

To find the formula of the compound formed by atoms A, B, and C in a cubic solid, we will follow these steps:

### Step 1: Determine the arrangement of A atoms
- A atoms form a close-packed arrangement, which is typically face-centered cubic (FCC).
- In an FCC structure, there are 8 corner atoms and 6 face-centered atoms.

**Contribution of atoms:**
- Each corner atom contributes \( \frac{1}{8} \) to the unit cell, and there are 8 corners.
