## Rebar Layout
**Bars in One Direction = floor((Dimension - 2 x Offset) / Spacing) + 1**
Rebar is placed in a grid pattern with bars running in both directions. The edge offset (typically 2 to 3 inches) keeps rebar away from the form edges for adequate concrete cover.

Exemplo Resolvido
20 x 12 ft slab, 12-inch spacing, 3-inch edge offset.
- Net length = 240 - 6 = 234 in
- Net width = 144 - 6 = 138 in
- Bars along length = floor(138/12) + 1 = 12
- Bars along width = floor(234/12) + 1 = 20
- Total = 12 + 20 = 32 bars
