## Concrete Column Volume
**Rectangular: V = W x D x H**
**Round: V = pi x (D/2) squared x H**
Convert all dimensions to consistent units. Add 2 ft per bar for lap splices and embedment into the footing. Vertical rebar count must be at least 4 for rectangular columns and 6 for round columns per ACI 318.

计算示例
12 x 12 in rectangular column, 10 ft tall, 4 bars.
- Area = 12 x 12 = 144 sq in = 1 sq ft
- Volume = 1 x 10 = 10 cu ft = 0.37 cu yd
- Rebar = 4 x (10 + 2) = 48 ft
