Landscape materials such as topsoil, mulch, and river rock are commonly sold by the rough yard, or partial yard. A yard of material is 27 cubic ft. In other words a 9'x3'x1' space. Check out our tips on mulching so that you do this important garden task the right way.

    Area Calculations: Draw your site as accurately as possible to scale. Use the following formulas to determine area: Rectangle: Area = length x width Circle: Area = 3.1416 x the square of the radius Triangle: Area = 1/2 x length of base x length of height Hint: If you are measuring odd or complex shapes, divide the area into combinations of rectangles, triangles, and/or circles. Measure these smaller areas and total the areas for them. Hint: To determine topsoil requirements for areas of varying grade you may have to estimate an average fill depth.
