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 cubic yards?

Here’s how to do this: Convert the dimension in inches to yards (6 inches ÷ 36 inches = 0.167 yards) Convert the dimensions in feet to yards (12 feet ÷ 3 = 4 yards) Multiply the three dimensions together to find the number of cubic yards (0.167 x 4 x 4 = 2.67 cubic yards).

## How much concrete do I need for a 10×10 slab?

## 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.

To prepare the base, cut the ground level to the proper depth to allow for the slab thickness.

## How do I calculate how much concrete I need?

Essentially you are solving for volume and then converting to cubic yards. 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.
