To calculate earthwork for a trapezoidal embankment using the Mean Area method:
1. *Surveying*: Survey the embankment area and take measurements at regular intervals to determine the cross-sectional areas.
2. *Divide into Sections*: Divide the embankment into several sections, each representing a portion of the embankment with a consistent shape.
3. *Compute Volumes*: Calculate the volumes of each section by multiplying the mean of the two cross-sectional areas by the distance between them.
4. *Mean Areas for Trapezoidal Sections*: For each trapezoidal section, calculate the mean area by averaging the area of the top and bottom trapezoidal faces.
5. *Earthwork Volume*: Multiply the mean area of each trapezoidal section by the distance between sections to get the volume of earthwork for each section. Sum up all the volumes to get the total earthwork volume for the embankment.
