You need to specify the slab's width and the length as well.
You will need about 0.8 cubic yards - 1 cubic yard is a safe bet.
To calculate the formula for a 4-inch concrete slab, you typically convert the thickness from inches to feet by dividing by 12. A 4-inch slab is 4/12 = 1/3 feet thick. When calculating the volume (cubic feet) for a slab, the formula is Volume = Length × Width × Thickness. If the slab covers an area of 80 square feet, multiplying that area by the thickness (1/3 feet) gives you 80 cubic feet.
70 feet! The answer is in the question!
Concrete is man-made.
The recommended footings for a concrete slab are typically made of reinforced concrete and should be at least 6 inches thick and extend below the frost line in your area to prevent shifting or cracking.
The recommended concrete slab thickness for a house foundation is typically 4 inches to 6 inches.
The recommended thickness for a driveway concrete slab is typically 4 inches.
The cross-sectional area of a concrete slab is the total area of the slab when viewed perpendicular to its length and width. To calculate the cross-sectional area, you multiply the length of the slab by the width of the slab. This measurement is crucial for determining the amount of concrete needed for a project and for ensuring the structural integrity of the slab.
To calculate the volume of concrete needed for a slab, you can use the formula: Volume = Area × Thickness. First, convert the thickness from inches to feet: 4 inches is 1/3 feet. Then, multiply the area (256 square feet) by the thickness (1/3 feet): 256 × (1/3) = approximately 85.33 cubic feet of concrete is needed for the slab.
The recommended thickness for a concrete slab is typically 4 inches for residential applications and 6 inches for commercial or heavy-duty use.

The recommended depth for the footer when constructing a concrete slab is typically around 12 inches.
One cubic yard of concrete can cover an area of approximately 81 square feet at a thickness of 4 inches. If you pour the slab at different thicknesses, the coverage area will change; for example, at 6 inches thick, one yard would cover about 54 square feet. It's important to calculate the desired thickness of your slab to determine the exact coverage area.
To calculate the volume of concrete needed for a slab that measures 74 inches long, 48 inches wide, and 4 inches thick, first convert the dimensions to feet: 74 inches = 6.17 feet, 48 inches = 4 feet, and 4 inches = 0.33 feet. Then, multiply the dimensions: 6.17 ft × 4 ft × 0.33 ft = approximately 8.16 cubic feet. Therefore, you will need about 8.16 cubic feet of concrete for the slab.
4 To 6 inches
The ideal thickness for a concrete slab when building a house is typically 4 inches to 6 inches. This thickness provides a strong and durable foundation for the structure.
