Quick Answer: How Many Yards Of Concrete Do I Need Formula

How do I figure out 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.

What’s the formula for figuring up concrete?

Calculating the volume for concrete requires using three dimensions: length times width (which is area) times the height (thickness) or L x W x H. If you are using feet as your standard unit of measurement, this formula will give you the volume of concrete in cubic feet.

How many yards of concrete do I need for a 24×24 slab?

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. Note: The Concrete Volume Calculator can also be used to determine yardage for aggregate products.
