Raised Garden and Planter Soil Calculator

• 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 ft³ 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.
