Enter a value for all fields

The **Area of a Concrete Slab** calculator computes the surface area of a rectangular slab.

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

- (
**w**) Width of the slab, - (
**L**) Length of the slab.

**Surface Area (A):** The surface area of the slab is returned in square feet (ft^{2}). However, this can be automatically converted into other area units (e.g. square meters) via the pull-down menu.

- Compute the
**Length of Rebar**needed for a slab. - Compute the
**Weight of Rabar**in a slab. - Compute the
**Surface Area**of a slab. - Compute the
**Surface Area of Concrete Forms**. - Compute the
