We take overt need to divide by two as we know the ground is flat in the zone where we need to fill we therefore do not average.C = height varian to fill level x the distanceC = 3*14.584C = 43.752Note1 We dont need to divide by two as we know the ground is flat in the zone where we need to fill we therefore do not average.Prismoidal Formula ApplicationVolume = (A+4B+C)*L/6V = 30.468 + (4*43.752) + 43.752 * 30.118 / 6V = (30.468 + 175.008 + 43.752) * 30.118 / 6V = (249.228 * 30.118) / 6V = 7506.249 / 6V = 1251.041 mEnvironmental engineer
