### Step-by-Step Solution:

1. **Identify Non-Zero Digits**:
- The digits in the number 12.024 are 1, 2, 0, 2, and 4.
- The non-zero digits are 1, 2, 2, and 4.

2. **Count Non-Zero Digits**:
- All non-zero digits (1, 2, 2, and 4) are significant.
- Count: 1 (from 1) + 1 (from 2) + 1 (from 2) + 1 (from 4) = 4 significant figures.

3. **Identify and Count Zeros**:
- The zero in 12.024 is between the non-zero digits (2 and 2).
