How do you calculate cubic feet in stone?

This formula should be used for any bulk material, i.e. mulch, loam, crushed stone, etc.

Measure square foot area (width x length)
Choose the desired depth of material (convert inches to feet) 1″ = .08 ft.
Square Feet Area x Depth (in feet) = Cubic Feet (width x length x depth)
Divide Cubic Feet by 27 to get Cubic Yards.

How do you find the square footage of a hole?

Once you have the length and width measurements, determine the square footage of the surface by multiplying the length times the width. For example, you are filling a hole that is 10 feet long and 4 feet wide, the total square footage is 40 square feet (10′ x 4′).

How much concrete do I need for a post hole?

Most fence post holes will need between 1 – 4 bags of concrete to securely hold the post in place. The best way to determine the size of the hole is: Diameter of the hole is 3 times the width of the fence post. Depth of the hole is one-third to half the above ground height of the fence post.

How much material does it take to fill a hole?

Calculate the volume of dirt needed to fill in the hole using pi (3.142) times the square of the radius times the depth. For this example, you would multiply 3.142 by the square of 30 by 30 to obtain the volume. This yields 3.142 times 900 inches times 30 inches, or 84,834 cubic inches.

How much dirt is in a hole that is 3ft by 4ft by 5ft?

How much dirt is there in a hole that measures two feet by three feet by four feet? None. A hole doesn’t have any dirt.

How to calculate the volume of concrete for a round hole?

Use these formulas to calculate volume or, for round holes, use our cylinder cubic yardage calculator . With the volume of the submerged post and the volume of the hole figured out, subtract the post volume from the hole volume and you will have the volume of concrete needed for each hole.

How to calculate the cubic feet of a hole?

Rectangular Hole. Measure one side of the hole to determine its width. Measure the adjacent side to determine the length. Lower the measuring tool into the hole and measure the height. Convert all measurements to feet before proceeding. Multiply the width by the length. Multiply the resultant value by the height to calculate the volume.

How to calculate the volume of river rock?

Our calculator is able to work with many units and does the appropriate conversions for you. Simply select the desired units, and the calculator will do the following conversions: Below, we provide three full examples detailing how the calculator finds the total volume, weight and cost.

How do you measure the depth of a hole?

Multiply the resultant value by Pi (3.14). This is the measurement of the hole’s base. Stick the measuring tool into the hole to measure the height. If the hole is very deep, lower a rope/string into the hole until it reaches the bottom. Mark the string at the spot where it is level with the top of the hole.

How to calculate the depth of dirt fill?

(You must estimate if the area is oblong.) Enter the width, length, and thickness (how deep you want the cover) of your rectangular area, or enter the diameter and depth (of the cover) of your circular area, click on whether you are measuring each designation in feet or inches (they do not all have to be the same), then click Calculate.

How to calculate the depth of a cubic yard?

For example, if you have one measurement that is 7’3″ you can enter that as 7.25 feet (3″/12″ = 0.25 ft). If you have a measurement of 245 cm you can also enter that as 2.45 m. Determine the depth of your material, say mulch, that you will put on this area generally using depth in inches
