📏 Dimension unit

All dimensions use same unit

📐 Slab & footing volume = length × width × thickness. Column volume = π × (diameter/2)² × height.
🧱 Bag yields (approx): 40lb → 0.3 ft³ (0.011 yd³), 60lb → 0.45 ft³ (0.0167 yd³), 80lb → 0.6 ft³ (0.0222 yd³). Numbers are rounded up to nearest whole bag.
