Area & Volume FAQs
How do I calculate gravel by square feet?
Find the area (length × width) in square feet, multiply by depth in feet for cubic feet, then divide by 27 for cubic yards.
How do I convert square feet to cubic yards of gravel?
Multiply square feet by depth-in-feet to get cubic feet, then divide by 27. Depth matters, the same area needs more gravel when deeper.
How many cubic feet in a cubic yard?
27 cubic feet make one cubic yard.
How much area does a cubic yard cover?
108 sq ft at 3 inches deep, 81 sq ft at 4 inches, and 54 sq ft at 6 inches.
