Cost Estimate for 27'x10' 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 270 sq ft at a depth of 6", the estimated cost is $787.50
$787.50
for 225 x 80lb bags
Truck Cost Estimate
Ready-mixed concrete costs on average $108.22 per cubic yard delivered. Using a concrete truck to cover 270 sq ft at a depth of 6", the estimated cost is $541.10
5 x $17.00 = $85.00
$541.10 + $85.00 = $626.10
*6 inch pours and under.
**Cost assumes subbase and general prep is done.
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.
So for a 10 cu/yd Truck Load - 5 cu/yd concrete = 55 x $17.00 = $85.00
$541.10 + $85.00 = $626.10
$626.10

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 27x10 area at 6 inches deep, you would need approximately 7.1 tons or 5 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 270 sq ft area, this may roughly cost $151.20 for wire mesh, $810.00 for thicker wire rebar mesh and $35.10 for fiber mesh.
*Reinforcing for 10 inch pours and under.How to Calculate Concrete Amount for 27x10 x6"
27 * 10 = 270 sq ft
6 / 12 = 0.5 ft depth
270 * 0.5 = 135 cu ft
135 / 27 = 5
= 5 cu/yd
How to Calculate Concrete Weight
5 * 3590 = 17950 lbs
Density of concrete used 2130 kg/m3or 133 lbs/ft3.
6 / 12 = 0.5 ft depth
270 * 0.5 = 135 cu ft
135 / 27 = 5
= 5 cu/yd
