## How many yards of concrete do I need calculator?

**CONCRETE CALCULATOR** FORMULA

Multiply the length by the width to determine square footage. Convert the thickness from inches to feet. Multiply the thickness in feet by the square footage to determine cubic feet. Convert cubic feet to cubic **yards** by multiplying by.037.

## How do you measure a yard of concrete?

Multiply the width times the length times the height (W × L × H), or use our volume **calculator** to find the cubic feet. Convert the volume to cubic **yards** from cubic feet. To do so, divide the cubic footage by 27 to get the **yards** of **concrete** needed.

## What is the formula for calculating concrete?

**Calculating** the volume for **concrete** requires using three dimensions: length times width (which is area) times the height (thickness) or L x W x H. If you are using feet as your standard unit of measurement, this **formula** will give you the volume of **concrete** in cubic feet.

## How much concrete do I need for a 10×10 slab?

For a **10 x 10 slab**, we’d suggest a mix with a capacity of about 4,000 pounds per square inch, or psi. This is basic for residential projects, and it can withstand traffic and support heavy loads.

## How much does 2 yards of concrete cost?

## How many bags of cement do I need for 100 square feet?

Ans.:- 7.6 no of **cement bags** (381.30 kgs) are required for **100 sq ft** rcc roof slab 4 inch thick m20 grade concrete. Ans.:- 7.6 **bags** (381.30 kgs), 9.5 **bags** (476.10 kgs) & 11.4 **bags** ( 570.8 kgs) **cement** are required for **100 sq ft** rcc roof slab 4 inch, 5inch & 6 inch thick respectively in m20 grade of concrete.

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

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 much is 4 yards of concrete cost?

Each cubic **yard of concrete costs** $119 to $147 per cubic **yard** delivered.

Short-Load **Concrete Prices**.

## How many bags of concrete make a yard?

Pure cement, sand and crushed rock all have about the same density, so a block of pure cement measuring 1 cubic yard of volume (about **3,600** pounds) will contain **45 bags** of cement.

## What is the correct mix for concrete?

In terms of the ratio for concrete, it depends on what strength you are trying to achieve, but as a general guide a standard concrete mix would be 1 part cement to 2 **parts sand** to 4 **parts** aggregates. For foundations, a mix of 1 part cement to 3 **parts sand** to 6 **parts** aggregates can be used.

## How much does 30 yards of concrete cost?

Use $90 per cubic **yard** as a ballpark figure for **concrete prices**, but **concrete** slab **cost** will vary by region. Also, expect a fee of about $60 per load for delivery from a **concrete** truck for **concrete cost**. There could be other fees for such things as Saturday **concrete** truck delivery and small loads.

## How do I calculate cubic meters of concrete?

1 **cubic meter** (1m3) can be visualised by drawing a cube 1 **meter** wide x 1 **meter** tall x 1 **meter** depth. To **calculate** the **concrete** volume of a **concrete** slab you multiply the length, width and depth of the **concrete** slab to get an estimate of the amount of **concrete** you need in **cubic metres m3**.

## How many square feet does an 80lb bag of concrete cover?

4 **sq feet** in that amount of **cement**.

## How many square feet does 10 yards of concrete cover?
