Instructions

  This calculator provides the following functions:

  • Volume of a Box Planter - Rectangular with vertical sides
  • Volume of a Tapered Rectangular Box - Rectangular with tapered sides
  • Volume of a Tapered Polygon Shaped Planter - Polygon base and top with any number (n) of even sides
  • Volume of a Triangular Shaped Planter (with vertical sides). 
  • Volume of a Hexagon Shaped Planter 
  • Volume of a Octagon Shaped Planter
  • Planting Soil Cost - Estimate of cost of soil.
  • Minimum Water Requirement - Estimate by volume of soil.
  • Maximum Water Required - Estimate by volume of soil.
  • Mulch to Cover Area
  • Mulch to Cover Circular Area
  • Mulch to Cover Rectangular Area
  • Mulch Cost Estimate
  • Bales of Straw to Cover Area
  • Garden (Area):  Many gardens have four straight sides.  This calculator lets you enter the lengths of the sides (a,b,c,d) and the diagonal (D) to compute the square footage of the garden.
  • Area Conversions:  Choose your area units (e.g. square feet) and enter the value.  Your answer will be echoed back to you.  Then choose other area units via the pull-down menu next to the answer.
  • Volume Conversions:  Choose your volume units (e.g. gallons) and enter the value.  Your answer will be echoed back to you.  Then choose other volume units (e.g. liters) via the pull-down menu next to the answer.
  • Conversions to Common Kitchen Units:  This takes any volume measurement (you choose the units) and converts it into house-hold kitchen units.  For example, 0.9 ft3 turns into 6 Gallons, 2 Quarts, 1 Pints, 1.5 Cups, 3 Tablespoons and 1.54 teaspoons.

The shapes dictate the geometric (3D) formulas needed to calculate the planter volume. 

Volume Options

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:  

  • 1 ft3 
  • 1.25 ft
  • 2.5 ft3  
  • 8 quarts
  • 32 quarts 
  • 64 quarts

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. 

Cost Estimates

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.

Units Conversions

The unit conversions include the following:

  • Area Unit Conversions:  With this function, one can enter an area in any unit, and then click on the results pull-down menu to convert that area to other units.
  • Volume Unit Conversions: With this function, one can enter an area in any unit, and then click on the results pull-down menu to convert that area to other units.
  • Kitchen Units:  This utility converts any volume in any units to units common with English kitchen utensils (gallons, quarts, pints, cups, cup fractions, tablespoons, and teaspoons).

Usage

This calculator can be used to answer the following questions:

  1. How much soil will my planter hold?
  2. How much water will my container hold?
  3. How much bulk potting soil do I need?
  4. How many bags of soil will I need?
  5. How much will the potting soil cost?
