How much area would 5 cf of rock cover?

To determine how much area 5 cubic feet (cf) of rock would cover, you need to know the depth of the rock layer you want to create. For example, if you spread the rock to a 1-inch depth, it would cover approximately 60 square feet (since 5 cf equals 60 cubic inches). If the depth is different, you can adjust the area accordingly by using the formula: Area = Volume / Depth.
