## How many bags of concrete does it take to fill a sonotube?

16 cubic feet / 0.6 cubic feet / **per bag** = 27 (80#) **bags of concrete** mix.

## How much concrete do I need calculator?

For concrete, the formula for volume is as follows: length x width x thickness. To determine how many bags of concrete you will need, divide the total cubic yards needed by the yield. Use the following yields per each bag size: **40 pound** bag yields.011 cubic yards.

## How deep should Sonotubes be?

Brace securely at top, middle and bottom of tube. There is no pour rate restriction below the joint, but you CANNOT pour a full liquid head up to 20 feet when using a “Joined” Finish Free Tube if the joint is below the 20 foot level.

## How do you calculate concrete for a round hole?

The **formula** for the **volume** of a **round hole** is pi r2 x depth. Or 3.14 x radius x radius x depth. The radius is half the width of the **hole**.

## How many bags of concrete do I need for a 4×4 post?

Mix two 50lb bags of concrete with water in a mixing tub or 5-gallon bucket. Add concrete into the hole and around the 4” x 4”. Depending on your climate, let concrete set up for **24 – 48** hours.

## How many 80lb bags of concrete makes a yard?

If you’re using **80lb bags of concrete**, you’ll need 45 **bags** to **make a yard**.

## How many bags of concrete do I need for a 10×20 slab?

A 60-pound **bag** yields. 017 cubic yards, and an 80-pound **bag** yields. 022 cubic yards. For a 10 x 10 **slab**, you **would need** 77 60-pound **bags** or 60 80-pound **bags**.

## How much sand and cement do I need for 1 cubic meter of concrete?

Thus, the quantity of **cement** required for **1 cubic meter of concrete** = 0.98/0.1345 = 7.29 bags of **cement**. The quantities of materials for **1 m3 of concrete** production **can** be calculated as follows: The weight of **cement** required = 7.29 x 50 = 364.5 kg. Weight of fine aggregate (**sand**) = 1.5 x 364.5 = 546.75 kg.

## How do you calculate concrete meters?

**Calculating** Cubic **Metres**

If you took metric measurements, then multiply the length by the width by the depth (L x W x D) to find the volume needed in cubic **metres**. For measurements in centimetres, multiple the measurements by 100 to find the amount in **metres**.

## Do you leave sonotube in ground?

No, it’s not a problem to **leave** the **Sonotube** and its plastic “Square Foot” (like these) in the **ground** forever.

## How many posts do I need for a 12×16 deck?

A standard **deck** will need four footings parallel to the house, but they will need to be temporarily braced by 6 inch-by-6 inch **posts**.

## How many bags of concrete do I need for a 6×6 post?

As I recall, a 60# **bag of concrete** is about. 5cf, so you’d need 3 **bags** per hole.

## How many 20kg bags of premixed concrete do you need?

For jobs where a stronger rated concrete is needed, youmay consider our High Strength Concrete Mix for your concreting purposes. Yield: One 20kg bag will cover an area of 1.1m2 to a depth of approximately 10mm. Or **108** x 20kg bags equates to one cubic metre of mixed concrete.

## How much does it cost for 10 yards of concrete?

The average cost of concrete delivery is **$119** to **$147** per cubic yard for a full 10-yard truckload of ready-mix concrete, and **$172** per yard for a short-load of less than 10 yards.
