Answer

Estimated Concrete Volume

2.556 cubic yards

69 cubic feet

Estimated Weight of Concrete

## 4.59 tons

Covering 138 sq. ft. at 6" depthChange dimensions

Optional 10% extra concrete

for waste allowance

10% = 0.26 cubic yards

Total Concrete with 10% = 2.81 cubic yards

for waste allowance

10% = 0.26 cubic yards

Total Concrete with 10% = 2.81 cubic yards

## Cost Estimate for 6'x23' 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 138 sq ft at a depth of 6", the estimated cost is

**$402.50****$402.50**

for 115 x 80lb bags

## Truck Cost Estimate

Ready-mixed concrete costs on average $108.22 per cubic yard delivered. Using a concrete truck to cover 138 sq ft at a depth of 6", the estimated cost is

7.4 x $17.00 = $125.80

$276.56 + $125.80 =

*6 inch pours and under.

**Cost assumes subbase and general prep is done.

**$276.56**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.

7.4 x $17.00 = $125.80

$276.56 + $125.80 =

**$402.36****$402.36**

## 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 6x23 area at 6 inches deep, you would need approximately **3.63 tons** or **2.56 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 **138 sq ft area**, this may roughly cost **$77.28** for wire mesh, **$414.00** for thicker wire rebar mesh and **$17.94** for fiber mesh.

How to Calculate Concrete Amount for 6x23 x6"

6 * 23 = 138 sq ft

6 / 12 = 0.5 ft depth

138 * 0.5 = 69 cu ft

69 / 27 = 2.5555555555556

= 2.556 cu/yd

How to Calculate Concrete Weight

2.5555555555556 * 3590 = 9174.44 lbs

Density of concrete used 2130 kg/m

6 / 12 = 0.5 ft depth

138 * 0.5 = 69 cu ft

69 / 27 = 2.5555555555556

= 2.556 cu/yd
