What thickness can one yard of concrete typically cover?

One yard of concrete typically covers an area depending on its thickness and dimensions. When calculating coverage, one yard of concrete is equivalent to 27 cubic feet. Given the standard thickness options presented, the calculation for a 4-inch thickness shows that one yard of concrete can cover an area of 81 square feet.

The calculation is based on converting inches to feet: 4 inches is equal to 1/3 of a foot. To find out how much area one cubic yard can cover at this thickness, you divide the total cubic feet in a yard (27 cubic feet) by the thickness in feet (1/3). This results in 27 divided by (1/3), which equals 27 multiplied by 3, or 81 square feet.

Thus, the answer of 4 inches as the thickness is appropriate as it provides a practical and common measurement that concrete is poured at, especially for patios, driveways, and sidewalks.
