Bag Cost Estimate
Truck Cost Estimate
Most concrete truck companies have a 1 to 4 cubic yard minimum order. We recommend contacting your nearest concrete suppiler for an estimate. So for this estimate the 1 yard minimum will be used.
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 - 1 cu/yd of concrete = 9.00
9.00 x $17.00 = $153.00
$153.00 + $108.22 = $261.22
With a brief look, a 5x5 area at 6 inches deep, you would need approximately 0.66 tons or 0.46 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 25 sq ft area, this may roughly cost $14.00 for wire mesh, $75.00 for thicker wire rebar mesh and $3.25 for fiber mesh.*Reinforcing for 10 inch pours and under.
6 / 12 = 0.5 ft depth
25 * 0.5 = 12.5 cu ft
12.5 / 27 = 0.46296296296296
= 0.463 cu/yd

5 ft x 5 ft x 6" Concrete Summary
How many concrete bags would I need for a 5 ft x 5 ft x 6" slab? 20.8 x 80lb Concrete bags.
How much does it cost to pour a 5'x5' x6" slab? Ready-mix costs approx $211.60.
How do you calculate concrete volume? Formula ((width x length) x (depth in inches / 12)) / 27 = total cubic yards. See our how to here
This Concrete calculator can be used for a slab, floor, garage, block, wall, driveway, patio, countertop, footings, foundation, pool or basement, and most rectangular areas.
