**How much concrete do i need for a 10 × 10 slab** | how many yards of concrete do I need for a 10 × 10 slab | how many bags of concrete do I need for a 10 × 10 slab.

Concrete ready mix made of blended mix of Portland cement, sand gravel and other approved ingredient, generally, dry ready mix concrete are available in different bag size and weight condition like 40lb, 60lb bag, 80lb bag, 90lb bag and etc.

Regardless of size you need to calculate the volume of concrete in cubic yard before ordering the mixed concrete. Volume is calculated by multiplying length, width and depth of slab. In this article we have to calculate required quantity of concrete in cubic yard for 10 × 10 (100 sq ft) slab of 4 inch, 5 inch or 6 inch thick.

Generally standard thickness of slab is 4 inch thick in normal conditions, if 10 × 10 slab have heavy traffic and heavy load, you should take depth 5 or 6 inch thick.

Weight of Ready mix concrete in dry condition is about 133 lbs per cubic foot, 3600 lbs per cubic yard, or 2136 kg per cubic meter. The weight of concrete is determined by its density, which can vary based on the amount of aggregate, water, and air in the mix.

In United States, based on Imperial measurement system, 1 cubic yard is unit of measurement of volume represented by 3 feet long by 3 feet wide by 3 feet depth (3’×3’×3′ = 27 cubic feer), so 1 cubic yard is equal to 27 cubic feet.

**How much concrete do I need for a 10 × 10 slab**

To determine the how much concrete do I need for a 10 × 10 slab solve in following steps:-

Step 1 :- calculate the volume in cubic feet:- We have given 10 × 10 slab (length × width), consider it is 4 inch thick, 4 inch = 0.33 feet.

To determine the volume of slab, you need to multiply all dimensions, such that = 10′ × 10′ × 0.33′ = 33 cubic foot.

Step 2 :- converting cubic feet into cubic yard:- Now converting into cubic yard, you should divide it by 27, because 1 cubic yard = 27 cubic foot, so volume of concrete you needed for 10 × 10 slab 4 inch thick in cubic yard = 33/27 = 1.22.

Step 3 :- Add 10% extra :- considering extra 10% wastage during mixing and pouring, so 10% of 1.22 cubic yard =0.122, add 1.22 + 0.122 = 1.34 cubic yard.

**Q 1) How much concrete do I need for a 10 × 10 slab**

Using 4 inch thick, 10 × 10 slab in normal load or standard condition for making sidewalks, curbs, steps, ramp, walkway and patio, Generally, 1.34 cubic yard or 36.18 cubic foot of concrete quantity are needed for a 10 × 10 slab 4 inch thick.

5 inch or 6 inch thick slab is ideal for heavy load and heavy traffic, for 5 inch thick, 10 × 10 slab, you need about 1.697 cubic yard or 45.827 cubic feet of ready mix concrete and for 6 inch thick, 10 × 10 slab, you need about 2.036 cubic yard or 55 cubic feet of ready mix concrete.

**Q2) how many yards of concrete do I need for a 10 × 10 slab**

for sidewalks, curbs, steps, ramp, walkway and patio which are made of 10 × 10 slab 4 inch thick, generally you need around 1.34 cubic yard of ready mix concrete.

5 inch or 6 inch thick slab is ideal for heavy load and heavy traffic, for 5 inch thick, 10 × 10 slab, you need about 1.697 cubic yard of ready mix concrete and for 6 inch thick, 10 × 10 slab, you need about 2.036 cubic yard of ready mix concrete.

**Q3) how many cubic foots of concrete do I need for a 10 × 10 slab**
