Give data
Width=B
Height=d
Slope =S:1
What is the base of triangle..?
Slope = height/ base or rise/ run
Slope=S/1= d/base
n base = d
base=d/n
Area of cross-section= Area of rectangle+ Area of triangle
Bd+ 1/2 base × height
Bd+ 1/2 × d/n× d
Bd+d²/n

AREA OF CROSS SECTION =Area of rectangle + 2* Area of triangle.
=BD+SD^2.
In case of cutting side slope is 1:1.
In case of Filling side slope is 2:1 (H:V).
