What material and in what quantity would you need to construct a concrete footpath 100m long?

To construct a concrete footpath that is 100 meters long, you would typically need to determine the width and thickness of the path. For example, if the path is 1 meter wide and 10 cm (0.1 meters) thick, you would need 10 cubic meters of concrete (100m x 1m x 0.1m = 10m³). To account for waste and variations, it's advisable to order about 10-15% more concrete, so approximately 11-12 cubic meters would be ideal.
