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 216 sq ft at a depth of 6", the estimated cost is $630.00

for 180 x 80lb bags
Truck Cost Estimate
Ready-mixed concrete costs on average $108.22 per cubic yard delivered. Using a concrete truck to cover 216 sq ft at a depth of 6", the estimated cost is $432.88
6 x $17.00 = $102.00
$432.88 + $102.00 = $534.88
*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 - 4 cu/yd concrete = 66 x $17.00 = $102.00
$432.88 + $102.00 = $534.88
$534.88

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 9x24 area at 6 inches deep, you would need approximately 5.68 tons or 4 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 216 sq ft area, this may roughly cost $120.96 for wire mesh, $648.00 for thicker wire rebar mesh and $28.08 for fiber mesh.
*Reinforcing for 10 inch pours and under.How to Calculate Concrete Amount for 9x24 x6"
9 * 24 = 216 sq ft
6 / 12 = 0.5 ft depth
216 * 0.5 = 108 cu ft
108 / 27 = 4
= 4 cu/yd
How to Calculate Concrete Weight
4 * 3590 = 14360 lbs
Density of concrete used 2130 kg/m3or 133 lbs/ft3.
