Quantity of muck (m3) = excavation area of muck (m2) × excavation depth of muck (m). The specific calculation steps are as follows.

1, according to the actual situation of the project, calculate the area and depth of muck to be excavated.

2. According to the calculation results, the excavation area of muck (unit: square meter) and the excavation depth of muck (unit: meter) are substituted into the calculation formula for calculation.

3. According to the calculation results, the amount of muck (in cubic meters) is the total amount of muck needed.
