Volume (ft³) = Width × Length × Depth
Area (ft²) = π × (Diameter/2)²; Volume (ft³) = Depth × Area
Volume (ft³) = Thickness × Length × Height
Volume (ft³) = Width × Length × Depth
Volume (ft³) = Width × Length × Height
Area (ft²) = π × (Diameter/2)²; Volume (ft³) = Height × Area
Platform volume = PlatformDepth × (RiseHeight × NumberOfSteps) × Width
Steps volume = RunDepth × (RiseHeight × Step#) × Width, summed from Step 1 to (N-1).
Curb volume = CurbDepth × (CurbHeight + FlagThickness) × Length
Gutter volume = GutterWidth × FlagThickness × Length
