`V = ( L * W * D )`

Enter a value for all fields

The **Volume of Concrete in a Slab** calculator computes the volume of concrete in a rectangle (square) slab. The value is function of the surface area (length * width), and the depth.

**INSTRUCTIONS:** Choose units and enter the following:

- (
**L**) Length of Slab - (
**W**) Width of Slab - (
**D**) Depth of Slab

**Volume of Concrete (V):** The calculator returns:

- V - Volume of concrete in cubic yards, and the equivalent volume in number of:
- 40lb bags
- 60lb bags
- 80lb bags

- A - Surface Area of the slab in square feet.
- Wtr - Water needed for concrete in gallons
- FB - Length of the form boards in feet.

However, these can be automatically changed to compatible units via the pull-down menu.

The Volume of Concrete in a Slab calculator compute the volume (3 dimensional space) of a concrete slab through the following equation:

V = L ⋅ W ⋅ D

where:

- V = volume
- L = Length of Slab
- W = Width of Slab
- D = Depth of Slab

The calculator converts the parameters into feet and computes the volume in cubic feet. It then uses the cubic feet to return volume in cubic yards for bulk concrete delivery, and divides it by the volume of the different sizes of concrete in bags. The most common are 40lb, 60lb and 80lb bags.
