The Garden Stone for 5 Sided Area calculator estimates cubic feet and number of units (e.g., bags) of garden stone to cover a five sided shaped area.
INSTRUCTIONS: Choose units and enter the following:
- (A) Length of Side A
- (B) Length of Side B
- (C) Length of Side C
- (D) Length of Side D
- (E) Length of Side E
- (F) Length of Diagonal F
- (G) Length of Diagonal G
- (d) Depth of Stone
- (BV) Volume Stone per Unit
- Bags: 0.4 ft3, 0.5 ft3, 1.0 ft3
- Bulk: 0.5 yd3, 1.0 yd3
Number of Units of Stone (nB): The calculator returns the returns the number of units of stone, the volume of stone in cubic feet, and the area covered in square yards. However, these can be automatically converted to compatible units via the pull-down menu.
The Math / Science
Very few yards are perfect rectangles. By using the length of the sides and diagonals, this calculator uses Heron's formula to compute the area (A). Volume of stone is simply area times depth. The number of bags is volume divided by the bag size.

Garden Stone Information
When purchasing river stone or other types of landscaping stone, the most common units and delivery sizes are:
- Cubic Yards: This is the standard unit for measuring bulk landscaping materials like river stone. One cubic yard is equal to 27 cubic feet.
- Tons: Some suppliers sell stone by weight. One ton of river stone typically covers about 80-100 square feet at a 2-inch depth, depending on the size of the stone.
Common Delivery Sizes:
- Half Yard to Full Yard: Smaller residential projects often order in increments of half or full cubic yards.
- 1-10 Tons: Larger landscaping projects might require multiple tons, and many suppliers deliver in truckloads of around 1 to 10 tons, depending on the customer’s needs.
- Bags: For smaller projects, river stone may be sold in bags, typically around 0.5 to 1 cubic foot per bag.
Stone Sizes:
- Pea Gravel: 1/4" to 3/8"
- Small River Stone: 3/4" to 1 1/2"
- Medium River Stone: 1 1/2" to 2 1/2"
- Large River Stone: 3" to 5" or larger
Garden stone is available in most DIY stores such as Home Depot, Menards and Lowes. Because stone is heavy, these garden stone products often comes in relatively small bags of differing volumes such as:
- 0.4 cubic feet
- 0.5 cubic feet
- 1.0 cubic feet
The size of the stones usually range from pea sized to river stones that are about the size of grapefruits.

Land Size Calculators
Three Sided Land Size: Computes the square feet, acres and perimeter in land with three straight sides.- Four Sided Land Size (squared): Computes the area in square feet and acres and perimeter in feet of rectangle land with roughly squared corners based on the length and width.
- Four Sided Land Size (not squared): Computes the area and perimeter of four sided land based on side lengths and a length of a diagonal.
- Five Sided Land Size: Computes the area and perimeter of a five sided land based on side lengths and the lengths of two diagonals.
- Circular Land Size: Computes the area of land in roughly circular shape based on the width (diameter).
- Simi-Circular Land Size: Computes the area of land in roughly semi-circular shape based on the width (diameter).
- Oval Shaped Land Size: Computes the area of land in roughly an oval (ellipse) shape based on the length and width.
- Human Paces to Feet and Meters: Estimates a length (feet, yards and meters) based on the number of paces a person takes to walk it and the approximate length of stride.
Walking Measurements
For large areas (lawns, gardens or fields), it may be hard to measure longer lengths, because you have no measuring device to make the long measurements (electronic device or long measuring tape or twine). In this case, an estimate can be achieved by using paces (your steps). 
To estimate a length with paces, you first have to make a reasonable estimate of a regular pace while in stride. To do this, put a mark on the ground, and step back several paces. Start walking to the mark, and start counting some number of paces past the mark (e.g. 10). A that point, stop and measure the length. For example a man of six feet tall with a normal stride walked 14 paces in 40 feet. That gave him a feet per pace of 2.857 feet per pace. To compute the Feet per Pace, CLICK HERE. You can then walk off the measurements, using a steady pace, and convert the Paces to Feet by CLICKING HERE. It's a rough estimation method, but not without it's uses.
Often it is required to put land pieces together to compute to total area of land. The land shown can be accurately computed by individual triangles. The area of 5 sided land function requires the diagonals that create three triangles that are summed to compute the area in a 5 sided piece of land.
