`V = ( "length" * "width" * "depth" )`

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**) This is the length of the slab - (
**W**) This is the width of the slab - (
**D**) This is the depth of the slab - (
**Units**) This is the output units. The SYSTEM output units are cubic (e.g. feet, yards, meters) or 60lb bags, 80lb bags.

**Volume of Concrete (V):** The calculator returns the volume of concrete in cubic yards. However, this can be automatically changed to compatible units via the pull-down menu.

**Cubic Yards in a Rectangle Slab:**This computes the volume of concrete in a rectangular shaped slab.**Volume of a Polygon Slab****Square Feet of a Rectangle Slab:**This computes the surface area of rectangular shaped slab.**Length of Rebar in a Rectangle Slab:**Computes the length of rebar in a rectangular shaped slab.**Weight of Rebar in a Rectangle Slab:**Computes the weight of rebar in a rectangular shaped slab.**Weight of Concrete by Cubic Yards:**This computes the weight of any volume of concrete.**Weight of Concrete and Rebar in a Slab**
