Step 1:-
Total length $= .23*3+6.23*2+2.33*2+3.23*4+1.83+1.43+6.46*3+5.23*2+4.23 \\
= 80.06 m$
No of junction = 12
$\text{Trapezoidal portion} \\
V= \bigg(\dfrac{A1+A2}{2}\bigg) *H \\
= \bigg(\dfrac{0.38*0.38+1.2*1.27*0.4}{2}\bigg) \\
= 0.333 m²$ $\hspace{6cm}$ $\text{Trapezoidal portion} \\ V= \bigg(\dfrac{A1+A2}{2}\bigg) *H \\ = \bigg(\dfrac{0.38*0.48+1.2*1.37*0.5}{2}\bigg) \\ = 0.456 m²$
$\text{Rectangular portion} \\
= 1.2*1.27*0.15 \\
= 0.22 m³ \\
VF1 = 0.333+0.22 \\
= 0.553 m³$ $\hspace{8.5cm}$ $\text{Rectangular portion} \\ = 1.2*1.37*0.15 \\ = 0.246 m³ \\ VF2 = 0.456 + 0.246 \\ = 0.702 m³$
