A: Divide inches by 12 (e.g., 6 inches = 0.5 feet).

Q2: How does this relate to bags of soil?
A: Most bagged soil is sold by cubic feet. Check bag labels and divide total volume by bag size.

Q3: What's a typical depth for garden beds?
A: 6-12 inches (0.5-1 ft) for most plants, 18 inches (1.5 ft) for deep-rooted vegetables.

Q4: How do I calculate area for irregular shapes?
