Answer

Estimated Concrete Volume

5.333 cubic yards

144 cubic feet

Estimated Weight of Concrete

## 9.57 tons

Covering 288 sq. ft. at 6" depthChange dimensions

Optional 10% extra concrete for waste allowance

10% = 0.53 cubic yards

Total Concrete with 10% = 5.87 cubic yards

10% = 0.53 cubic yards

Total Concrete with 10% = 5.87 cubic yards

## Cost Estimate for 12'x24' 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.

*6 inch pours and under.

**Cost assumes subbase and general prep is done.

## Bag Cost Estimate

Pre-mixed concrete bags cost on average $3.50 per 80lb bag. Using pre-mixed bags to cover 288 sq ft at a depth of 6", the estimated cost is

**$840.00****$840.00**

for 240 x 80lb bags

## Truck Cost Estimate

Ready-mixed concrete costs on average $108.22 per cubic yard delivered. Using a concrete truck to cover 288 sq ft at a depth of 6", the estimated cost is

4.7 x $17.00 = $79.90

$577.17 + $79.90 =

**$577.17**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.

4.7 x $17.00 = $79.90

$577.17 + $79.90 =

**$657.07****$657.07**

## 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 12x24 area at 6 inches deep, you would need approximately **7.57 tons** or **5.33 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 **288 sq ft area**, this may roughly cost **$161.28** for wire mesh, **$864.00** for thicker wire rebar mesh and **$37.44** for fiber mesh.

How to Calculate Concrete Amount for 12x24 x6"

12 * 24 = 288 sq ft

6 / 12 = 0.5 ft depth

288 * 0.5 = 144 cu ft

144 / 27 = 5.3333333333333

= 5.333 cu/yd

How to Calculate Concrete Weight

5.3333333333333 * 3590 = 19146.67 lbs

Density of concrete used 2130 kg/m

6 / 12 = 0.5 ft depth

288 * 0.5 = 144 cu ft

144 / 27 = 5.3333333333333

= 5.333 cu/yd

How to Calculate Concrete Weight
