`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 the slab - (
**W**) Width of the slab - (
**D**) Depth of the 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.

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