Assumes all cut and fill slopes are 2.1 for simplicty
Cut at High Side

Height of Fill at Face
h1 %,
w
Width of Cut
Fill area above transition = h1(2h1) + h1(w)
Fill area below transition;
total width of fill (dam) = 2h1 + w + 2h2
height below transition = h2-h1,
area = (width*height)/2 - height x height
