Is it possible to determine how many tons of gravel are needed to fill in a 400 feet long sidewalk? The thickness of the sidewalk is to be 2 inches thick.

It would depend on two parameters:

1. The sidewalk width.
2. The gravel type, i.e. how many pounds per sq. feet per 1 inch.

Follow the link below for the gravel calculator:

The calculations below was performed for:

1. The sidewalk width: 6 feet or 72 inches
2. The regular gravel, 7 lbs per square feet per 1 inch depth:
3. The sidewalk length 400 feet or 4800 inches

The calculation result follows:

33600.00 lbs or 15245.79 kg or 15.3 tons.

Make sure to find out the exact characteristics of the gravel you are planning to use first.
