The Raised Planter Calculator provides the volume Planter Shapes Rectangular Box Tapered Rectangular Tapered Polygon triangular planter hexagon planter Octagon Plantercircular planter and associated potting or garden soil cost to fill a planter, the amount of mulch or straw needed for coverage of the surface of the planter and the watering needed for different shaped planters (see diagrams). It also includes convenient unit conversions.
Theprovides the following functions:
The shapes dictate the geometric (3D) formulas needed to calculate the planter volume.
The answer to the volume equations default to ft3, but can also be converted to any of vCalc's standard volume units (e.g. cubic meters).
In addition to the SYSTEM units, these formulas proved the volume in non-standard units including "bags". The bag sizes are based on common bag sizes used for potting soil and include the following based on a survey of Home Depot's and Lowe's web sites. That survey showed that potting soil usually comes in a few standard size bags:
To get your answer in the number of bags needed, click the UNITS button labelled SYSTEM and select the bag size you wish. vCalc will convert your answer from standard volume units (e.g. cubic feet) to the number of bags of that size.
To use the Planting Soil Cost equation, first calculate the volume to be filled (above). Use the calculated volume as input to the cost equation, and choose whether you want Garden Soil or Potting Mix. The equation uses the volume info and the latest pricing data from the vCalc pricing data table (see link below), to proved a cost estimate using the large bags of filler. As a general rule, the cost per ft3 will be greater with the smaller bags. Other retail information is also available in that formula including the store used in the estimate and date of the cost survey.
The unit conversions include the following:
This calculator can be used to answer the following questions:
