Estimated Concrete Volume

3.167 cubic yards

85.5 cubic feet

Estimated Weight of Concrete

## 5.68 tons

Covering 171 sq. ft. at 6" depthChange dimensions

Optional 10% extra concrete

for waste allowance

10% = 0.32 cubic yards

Total Concrete with 10% = 3.48 cubic yards

for waste allowance

10% = 0.32 cubic yards

Total Concrete with 10% = 3.48 cubic yards

## Cost Estimate for 19'x9' x6"

Purchasing ready-mix concrete is by far the easiest way to mix concrete for medium to large projects and can even be used on smaller projects as well. We have provided a cost comparison between ready mix and DIY concrete premix bags to give you a rough ballpark estimate.

## Bag Cost Estimate

Pre-mixed concrete bags cost on average $3.50 per 80lb bag. Using pre-mixed bags to cover 171 sq ft at a depth of 6", the estimated cost is

**$500.50****$500.50**

for 143 x 80lb bags

## Truck Cost Estimate

Ready-mixed concrete costs on average $108.22 per cubic yard delivered. Using a concrete truck to cover 171 sq ft at a depth of 6", the estimated cost is

6.8 x $17.00 = $115.60

$342.70 + $115.60 =

*6 inch pours and under.

**Cost assumes subbase and general prep is done.

**$342.70**Concrete trucks may also charge a **"short load"** fee for partially filled loads. Short load fees are charged at about $17 for every yard not used on the truck.

6.8 x $17.00 = $115.60

$342.70 + $115.60 =

**$458.30****$458.30**

## Concrete Extras

A well-compacted

**subbase**provides a strong foundation for concrete to lay on. We recommend you contact your nearest concrete supplier for their recommendations on whether you need a subbase, base depth, and rock type.With a brief look, a 19x9 area at 6 inches deep, you would need approximately **4.5 tons** or **3.17 cubic yards of gravel**.

**Concrete reinforcing** is also recommended in high traffic areas and medium to large areas. **Wire mesh** on average costs **$0.56 per sq ft** and **fiber mesh** costs **$0.13 per sq ft**.

So for your **171 sq ft area**, this may roughly cost **$95.76** for wire mesh, **$513.00** for thicker wire rebar mesh and **$22.23** for fiber mesh.

How to Calculate Concrete Amount for 19x9 x6"

19 * 9 = 171 sq ft

6 / 12 = 0.5 ft depth

171 * 0.5 = 85.5 cu ft

85.5 / 27 = 3.1666666666667

= 3.167 cu/yd

How to Calculate Concrete Weight

3.1666666666667 * 3590 = 11368.33 lbs

Density of concrete used 2130 kg/m

6 / 12 = 0.5 ft depth

171 * 0.5 = 85.5 cu ft

85.5 / 27 = 3.1666666666667

= 3.167 cu/yd

How to Calculate Concrete Weight

3.1666666666667 * 3590 = 11368.33 lbs
