**Triangle: Height x length divided by 2 = square footage**

**Circle: Radius (center to edge) x radius x PI (3.141) = square footage**

**Use the guide on the left to estimate the yards your project requires or call us at ****509-465-1819.**** We are happy to assist you!**

**How do I estimate how much landscaping material is needed?****Measure the length and width of the rectangular area to be covered (in feet) and multiply them by each other. This is your square footage. For instance a 10' by 25' area is 250 square feet, or a 10' by 10' is 100 square feet. Now for a common 3" depth divide the total square footage by 108 to estimate the yards needed for coverage . For example , 100 square feet divided by 108 is .93- so about 1 yard.**

** For ****1"**** coverage, divide the square footage by ****324**

** For ****2"**** coverage, divide the square footage by ****162**

** For ****3"**** coverage, divide the square footage by ****108**

** For ****4"**** coverage, divide the square footage by ****81**

** For ****5" ****coverage, divide the square footage by ****65**

** For ****6"**** coverage, divide the square footage by ****54**

** For ****7"**** coverage, divide the square footage by**** 46**

** For ****8"**** coverage, divide the square footage by ****40**

** For**** 9"**** coverage, divide the square footage by ****36**
