🔹 Concrete Formula Reference

For those curious about the math, here are some standard concrete volume formulas:

• Slab / Rectangular Structure: Volume = Length × Width × Thickness

• Cylindrical Column: Volume = π × Radius² × Height

• Wall: Volume = Length × Height × Thickness

• Staircase (approximation): Volume = Number of Steps × (Tread × Riser × Width)

The calculator applies these formulas automatically, so you don’t have to.
