Comment ça marche

  1. 1

    Convert depth from inches to feet by dividing by 12.

  2. 2

    Multiply length by width to get the area in square feet.

  3. 3

    Multiply the area by the depth in feet to get volume per unit.

  4. 4

    Multiply by the number of units to get total volume.

length * width * (depth / 12) * units

Questions fréquentes

How do I account for waste or overage?

Add 5-10% to the total volume to cover spillage, uneven subgrades, or slight over-excavation.

Can I use this for round columns?

No, this calculator is for rectangular or square shapes. For round columns, use the formula π × radius² × height.

What if my dimensions are in meters?

Convert meters to feet first (1 m = 3.28084 ft) or use the cubic meters result after entering feet.

Formules

Les mathématiques derrière cette calculatrice, écrites pour que vous puissiez vérifier le résultat.

Rectangular Volume

V = L × W × H

Multiply length, width, and height (all in the same units) to get the volume.

Example:

Input: L=10 ft, W=10 ft, H=4 in (0.333 ft)

Calculation: 10 × 10 × 0.333

Result: 33.3 ft³

Cas d'utilisation réels

Où ce calcul apparaît dans la vie quotidienne.

Slab Foundation

Determine concrete needed for a house slab or patio.

Example: 20 ft × 30 ft slab, 4 in thick

Footings

Calculate concrete for continuous footings under walls.

Example: 40 ft long, 1 ft wide, 1 ft deep

Multiple Piers

Estimate concrete for several identical piers or posts.

Example: 10 piers, each 1 ft × 1 ft × 3 ft

Conseils et erreurs courantes

Tips

  • Always measure in the same unit system to avoid errors.
  • Order a little extra concrete (5-10%) to avoid running short.
  • Check with your supplier for minimum order quantities.
  • Use the cubic yards result when ordering from a ready-mix company.

Common Mistakes to Avoid

  • Forgetting to convert inches to feet before multiplying.
  • Not multiplying by the number of identical units.
  • Using outside dimensions when inside dimensions are needed.

Hypothèses et limites

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