How do you convert LF to CY?

Length in feet multiplied by width in feet multiplied by height in feet divided by 27 equals cubic yards needed.

How do you calculate concrete for a round hole?

To find cubic metres needed to fill a round hole

EXAMPLE: How much concrete is needed to fill 5 holes 1200mm deep and 1050mm round?
ANSWER: One hole takes 1.039 cubic metres, therefore 5 holes = 5 x 1.039 = 5.195. ( say 5.2 cubic metres)
NOTE: When the Diameter of a hole is doubled, it takes 4 times more concrete.

How big should screw hole be?

For most hardwoods, the pilot hole should be at least as large as the screw’s minor diameter. If the screw has deep threads, or the wood is very hard, the pilot hole should be another 1/64-in. larger than the minor diameter. For softer woods, the pilot hole can be 1/64-in.

How many bags of cement 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 big of a hole do you need for a post hole?

If you’re not sure what size hole to dig, a rule of thumb is to use a hole diameter 3 times the post diameter and 1 ⁄ 3 as deep as the post height. See below for more information.

How big of a hole do you need for a fence?

So, a 6’ high fence needs holes a minimum of 2’ deep. Order additional material to account for settling and spillage. If you have a lot of posts to set, it may pay you to mix the concrete yourself. Or, if you need a cubic yard or more, order mixed and delivered.

How big of a hole should I Dig for concrete?

If you’re not sure what size hole to dig, a rule of thumb is to use a hole diameter 3 times the post diameter and 1⁄3 as deep as the post height. See below for more information.

How to calculate the volume of a post hole?

First, you need to calculate the volume for the post hole. Then calculate the volume for the part of the post that will be submerged in the hole. Make sure all your units are the same! To easily use the table above, convert your units to feet if they aren’t already.

How big is the deepest hole in the Earth?

Earth’s deepest artificial hole stretches 40,000 feet below the surface — and it’s only covered by a rusty metal lid.

How to calculate how long to dig a hole?

Divide the hole volume by the shovel volume. This result is the number of shovel loads needed to complete the task. If each shovel load is 0.5 cubic feet and you need to dig out 50 cubic feet, the number of shovel loads needed will be 100 — 50 cubic feet to move divided by 0.5 cubic feet per shovel load.

How big is the well to Hell Hole?

The Kola Superdeep Borehole is 23 centimeters (about 8.7 inches) in diameter and its metal lid is welded on so it is unlikely that anyone would ever fall down it. Locals in the area say that the hole is so deep you can hear the screams of people being tortured in hell, hence its nickname being “the well to hell.”

How do you measure the depth of a hole?

Place a shovel full of earth into a box to determine the volume of dirt removed by each shovel load. Depending on the size of each shovel load, the box could be as small as a shoe box or as large as a milk crate. The goal is to get a full shovel load into a box so that you can measure the depth of the dirt.
