How do I figure how many yards of concrete I need?
How do I calculate how much concrete I need for a slab?
- Measure the area in feet.
- Multiply length by width, and then by thickness.
- Divide the resulting number by 27 to find cubic yards.
How do I calculate how much concrete I need for a slab?
For concrete, the formula for volume is as follows: length x width x thickness….Here’s what the math looks like for a 10′ by 10′ concrete patio:
- 10 x 10 = 100 square feet.
- 4 ÷ 12 = .33.
- 100 x .33 = 33 cubic feet.
- 33 x .037 = 1.22 cubic yards.
How many yards of concrete do I need for a 24×24 x4 slab?
7.11 yards
For example, for a concrete slab that is 24′ X 24′ X 4”, simply enter 4 in the Thickness/Depth field, 24 in the Width field, and 24 in the Length field. Click “Calculate”. Your answer should be 7.11 yards.

How many bags of concrete do I need for a slab?
You’ll also get the number of 40-pound, 60-pound, or 80-pound bags of concrete are needed for the project. For example, a 10′ x 10′ slab that is 4″ thick will need an estimated 1.23 yards 3 or 75 60lb bags of concrete and will cost roughly $140.
How much does it cost to lay a 10×10 concrete slab?
For example, a 10′ x 10′ slab that is 4″ thick will need an estimated 1.23 yards 3 or 74 60lb bags of concrete and will cost roughly $100.
How do you calculate how many yards of concrete do I Need?
Multiply the width times the length times the height (W × L × H), or use our volume calculator to find the cubic feet. Convert the volume to cubic yards from cubic feet. To do so, divide the cubic footage by 27 to get the yards of concrete needed. [1] Round up to the nearest yard as most suppliers will likely not sell fractions of a yard.
How much concrete do I need to build a 3′ porch?
So enter in the footing calculator, 6″ depth by 12″ width (always figure steps with a 12″ width) by 9′ length. This totals.17 cubic yards. The total concrete needed for the 3′ by 3′ porch will be.28 cubic yards. (.11 +.17 cubic yards =.28 cubic yards) Repeat this for added layers of steps.
