Estimated Concrete Volume

4.741 cubic yards

128 cubic feet

Estimated Weight of Concrete

## 8.51 tons

Covering 256 sq. ft. at 6" depthChange dimensions

Optional 10% extra concrete

for waste allowance

10% = 0.47 cubic yards

Total Concrete with 10% = 5.21 cubic yards

for waste allowance

10% = 0.47 cubic yards

Total Concrete with 10% = 5.21 cubic yards

## Cost Estimate for 16'x16' 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 256 sq ft at a depth of 6", the estimated cost is

**$745.50****$745.50**

for 213 x 80lb bags

## Truck Cost Estimate

Ready-mixed concrete costs on average $108.22 per cubic yard delivered. Using a concrete truck to cover 256 sq ft at a depth of 6", the estimated cost is

5.3 x $17.00 = $90.10

$513.04 + $90.10 =

*6 inch pours and under.

**Cost assumes subbase and general prep is done.

**$513.04**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.

5.3 x $17.00 = $90.10

$513.04 + $90.10 =

**$603.14****$603.14**

## 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 16x16 area at 6 inches deep, you would need approximately **6.73 tons** or **4.74 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 **256 sq ft area**, this may roughly cost **$143.36** for wire mesh, **$768.00** for thicker wire rebar mesh and **$33.28** for fiber mesh.

How to Calculate Concrete Amount for 16x16 x6"

16 * 16 = 256 sq ft

6 / 12 = 0.5 ft depth

256 * 0.5 = 128 cu ft

128 / 27 = 4.7407407407407

= 4.741 cu/yd

How to Calculate Concrete Weight

4.7407407407407 * 3590 = 17019.26 lbs

Density of concrete used 2130 kg/m

6 / 12 = 0.5 ft depth

256 * 0.5 = 128 cu ft

128 / 27 = 4.7407407407407

= 4.741 cu/yd

How to Calculate Concrete Weight
