Answer

Estimated Concrete Volume

1.444 cubic yards

39 cubic feet

Estimated Weight of Concrete

## 2.59 tons

5185.56 pounds

Covering 78 sq. ft. at 6" depthChange dimensions

Optional 10% extra concrete

for waste allowance

10% = 0.14 cubic yards

Total Concrete with 10% = 1.59 cubic yards

for waste allowance

10% = 0.14 cubic yards

Total Concrete with 10% = 1.59 cubic yards

## Cost Estimate for 13'x6' 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 78 sq ft at a depth of 6", the estimated cost is

**$227.50****$227.50**

for 65 x 80lb bags

## Truck Cost Estimate

Ready-mixed concrete costs on average $108.22 per cubic yard delivered. Using a concrete truck to cover 78 sq ft at a depth of 6", the estimated cost is

8.6 x $17.00 = $146.20

$156.32 + $146.20 =

*6 inch pours and under.

**Cost assumes subbase and general prep is done.

**$156.32**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.

8.6 x $17.00 = $146.20

$156.32 + $146.20 =

**$302.52****$302.52**

## 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 13x6 area at 6 inches deep, you would need approximately **2.05 tons** or **1.44 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 **78 sq ft area**, this may roughly cost **$43.68** for wire mesh, **$234.00** for thicker wire rebar mesh and **$10.14** for fiber mesh.

How to Calculate Concrete Amount for 13x6 x6"

13 * 6 = 78 sq ft

6 / 12 = 0.5 ft depth

78 * 0.5 = 39 cu ft

39 / 27 = 1.4444444444444

= 1.444 cu/yd

How to Calculate Concrete Weight

1.4444444444444 * 3590 = 5185.56 lbs

Density of concrete used 2130 kg/m

6 / 12 = 0.5 ft depth

78 * 0.5 = 39 cu ft

39 / 27 = 1.4444444444444

= 1.444 cu/yd

How to Calculate Concrete Weight
