工作原理

  1. 1

    Measure the length and width of the walkway in feet.

  2. 2

    Measure the thickness in inches.

  3. 3

    Multiply length × width × thickness (converted to feet) to get cubic feet.

  4. 4

    Divide by 27 to convert to cubic yards.

(length * width * (thickness / 12)) / 27

常见问题

How do I convert thickness from inches to feet?

Divide the thickness in inches by 12. For example, 4 inches = 4/12 = 0.333 feet.

Why divide by 27?

There are 27 cubic feet in one cubic yard (3 ft × 3 ft × 3 ft). Concrete is usually ordered by the cubic yard.

Should I order extra concrete?

It's common to add 5-10% for waste, spillage, or uneven subgrade. This calculator gives the theoretical volume.

工作原理

Estimates the volume of concrete needed for a rectangular walkway based on length, width, and thickness.

  1. Measure the length and width of the walkway in feet.
  2. Measure the thickness in inches.
  3. Multiply length × width × thickness (converted to feet) to get cubic feet.
  4. Divide by 27 to convert to cubic yards.

公式

此计算器背后的数学公式，供您核对结果。

Volume in cubic feet

V = L × W × (T / 12)

Multiply length and width (in feet) by thickness converted to feet.

Example:

Input: L=10 ft, W=3 ft, T=4 in

Calculation: 10 × 3 × (4/12) = 10 cubic feet

Result: 10 ft³

Convert to cubic yards

Y = V / 27

Divide the cubic feet volume by 27 to get cubic yards.

Example:

Input: V=10 ft³

Calculation: 10 / 27 ≈ 0.37

Result: 0.37 yd³

实际应用场景

此计算在日常生活中的应用。

Home walkway

Estimate concrete for a front or backyard path.

Example: 20 ft × 3 ft × 4 in ≈ 0.74 yd³

Garden path

Plan a narrow, decorative walkway.

Example: 15 ft × 2 ft × 3 in ≈ 0.28 yd³

Commercial sidewalk

Budget for a wider, thicker walkway.

Example: 50 ft × 5 ft × 6 in ≈ 4.63 yd³

提示与常见错误

Tips

  • Measure in feet for length and width, and inches for thickness.
  • Round up to the nearest quarter yard when ordering.
  • Add 5-10% extra for waste and uneven ground.
  • Check local building codes for minimum thickness requirements.

Common Mistakes to Avoid

  • Forgetting to convert thickness from inches to feet.
  • Using square feet instead of cubic feet.
  • Not dividing by 27 to get cubic yards.

假设与限制

  • Use the stated inputs and units.
  • Results are estimates for planning and education.
  • Check measurements and source data before making an important decision.
