Earthwork Volume by Average End Area

Easyearthworkaverage end area
Two earthwork cross-sectional end areas are 40 m2 and 60 m2, spaced 100 m apart. What is the volume by the average-end-area method?
  1. A1,000 m³
  2. B4,000 m³
  3. C5,000 m³
  4. D6,000 m³
Show solution

Answer: C. 5,000 m³

V = [(A₁ + A₂)/2]L = [(40 + 60)/2](100) = 5,000 m³.
