The **Soil for a Box (Raised) Planter** calculator computes the soil volume of a rectangular box shaped raised planter.

**INSTRUCTIONS**: Choose units and enter the following:

- (
**L**) Length of Planter - (
**W**) Width of Planter - (
**D**) Depth of Soil

**Raised Planter Volume (V)**: The calculator returns the volume of the planter in cubic feet, which can be automatically converted to compatible units via the pull-down menu. The calculator also returns the equivalent volume in number of standard size bags as follows:

- 1 cubic foot
- 1.25 cubic feet
- 2.5 cubic feet
- 8 quarts
- 32 quarts
- 64 quarts.

The soil for a box planter calculates the volume of a rectangular or box shaped planter. Enter the measurements of the planter: (l) length, (w) width and (d) depth of the interior of the box (see diagram), then this formula will provide the volume of the container. This answers the following questions:

- How much soil will my box planter hold?
- How much water will my box container hold?
- How much potting soil do I need?

If you do not intend to fill the container to the top, this formula will over estimate unless you use a depth (d) that matches your expected top surface inside the container. Unless it's a very large container, and/or you are only using a small portion of the container, the overage should be small.

**Potting Mix** is combination of organic materials (e.g., peat moss, aged bark and pumice) but no soil (dirt) that is used in lieu of potting soil to improve drainage. Because potting mix has no soil, it tends to be lighter than potting soil and provides a more sterile medium for plants with fewer disease carrying agents. Potting mix is most commonly recommended for plants in containers, and potting mix is particularly desirable for starting seeds.

**Garden Soil** is a gardening product sold that contains natural soil (dirt) comprised of mixture of loam, clay and sand. Garden soil is often used in raised gardens or planters as a healthy and easy medium for plants and seeds on top of the natural soil in one's yard. Garden Soil differs from Potting Mix in that garden soil contains real soil (dirt), where Potting Mix does not.

Always use local pricing for the most accurate cost! However, vCalc conducts a periodic pricing survey from nationally advertised retailers for various materials. The current **Garden Soil Price Survey** sample information for Garden Soil and Potting Mix is as follows:

**Soil for Box Planter**: Computes the soil volume of a rectangular box shaped raised planter.**Soil for Circular Planter:**Computes the volume and associated amount of soil for a circular planter (tapered or straight) based on the top diameter, base diameter and height.**Soil for Tapered Rectangular Planter**: Computes the volume and associated amount of soil needed for a tapered rectangular planter based on the top and bottom side lengths and height.**Soil for Polygon Shaped Planter**: Computes the volume of soil needed for a polygon shaped planter based on its shape (number of sides) and dimensions including the length of the sides and the height (depth).**Soil for Triangular Planter**: Computes the volume and associated amount of soil for a triangular shaped planter based on the side lengths (a, b, c) and (h) height.**Soil for Hexagon Planter**: Computes the volume and associated amount of soil for a hexagon shaped planter based on the length of the sides and height.**Soil for Octagon Planter:**Computes the volume and associated soil amount for an octagon planter based on the length of the sides and the height.**Soil Needed for 3 Tier Raised Garden**: Computes the amount of garden soil or potting mix needed for a three tier (step) raised garden based on the dimensions of the tiers.**Cost of Soil:**Computes the cost of a volume of soil base on unit price.**Water Requirement to Prepare Soil:**Estimates the minimum and maximum water range for plant growth to apply to initially moisten soil so that plants will not suffer from over or under watering.**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 ft^{3}turns into 6 Gallons, 2 Quarts, 1 Pints, 1.5 Cups, 3 Tablespoons and 1.54 teaspoons. This is useful in measuring soil and nutrient supplements.

**IMPORTANT NOTE**: Use the interior dimension of the planters and a height to match the depth of soil desired.
