Estimates the total volume of concrete and rebar needed to install a monolithic slab.
A monolithic slab takes its name from the one-pour design for both the slab and the footing. They are cast in place as one single component. This type of slab is suitable for warm climates.
Rows
Slab
-Length: Length of the slab.
-Width: Width of the slab.
-Depth: Depth of the slab.

Turndown (Rectangular)
-Width: Width of the rectangular portion of the turndown (see image).
-Depth: Depth of the rectangular portion of the turndown (see image).
Turndown (Triangular)
-Width: Width of the triangular portion of the turndown (see image).
-Depth:Depth of the triangular portion of the turndown (see image).
NOTE: Image below shows how the offset of where the triangular piece of the footing will be calculated.
