Final answer:
Loose sandy-gravel-type soil typically weighs around 100-120 lbs per square foot. Ordering by cubic yard and using a loader makes it easier to load materials like sand into a truck for yard or construction projects.
Step-by-step explanation:
The weight of loose sandy-gravel-type soil typically depends on the density of the material, which can vary based on factors like moisture content and compaction. However, a rough average for loose sandy-gravel soil is approximately 100-120 pounds per square foot when considering a depth of one foot. When ordering materials for yard work or construction projects, rather than getting bogged down in weight by the pound, many find it more efficient to order by volume, such as by the cubic yard. A cubic yard is a unit of measurement that represents a volume of 27 cubic feet. When loading materials like sand for a project, using a loader to scoop up and deposit the required amount directly into a truck is an easier method. This saves time and ensures accurate measurement for the project's need.
