| Section MethodAverage End area (Trapezoidal method) | 3 Methods of area Calculation
2 Volume calculation method
Volume = Lx 1/2 (A1 + A2)
Volume = L /6x (A1 +4Am+ A2) |
Mathematically, very good and hence adopted in majority of Civil Engineering Projects | Involves a lot of calculations | Used in most of the infrastructure ProjectsRoads, Irrigation Project, Rail Road Project |
| Average Method | Volume=Depth of cutting/filling* area | Easiest Method | Approximate, and when both cutting and filling are there, it cannot be applied | Used for very small projects |
| Box Method | Volume=Depth of cutting/filling* area for all the blocks | It Is very easy to calculate the area | 1. Box method will nullify volume when both cutting and filling are there in the same block 2. The incomplete boxes which are less than half are neglected for the Area Calculation |
Commonly used to find volume for leveling projects before the construction of a building |
| Contour Method | Volume Calculation2 Methods
Volume = Lx 1/2 (A1 + A2)
Volume= L (A + ÖAB+ B) / 3
|
Involves less mathematical calculation when a contour map with a contour area is available | Can only find filling volume (Used for finding Capacity of dams) | Used to find the capacity of Dams or Reservoirs |
