Step1: There are 2 types of footing $F_1 , F_2$

$\mathrm{Trapoziodal \ portion} \\ v=\bigg(\frac{A_1+A_2}{2}\bigg){\times} H \\ v= \frac{0.38{\times}0.38{\times}1.2{\times}1.5{\times}0.4}{2} \\ v=0.388 \ m^2 \\ \mathrm{Rectangular \ Potion} \\ =1.2{\times}1.5{\times}0.15 \\ =0.27 \ m^3 \\ V_{F_1}=0.388+0.27=0.65 \ m^3$ $\mathrm{Trapoziodal \ portion} \\ v=\bigg(\frac{A_1+A_2}{2}\bigg){\times} H \\ v\frac{0.38{\times}0.48+1.2{\times}1.8{\times}0.5}{2} \\ v=0.583 \ m^3 \\ \mathrm{Rectangular \ Potion} \\ =1.2{\times}1.8{\times}0.15 \\ =0.324 \ m^3 \\ V_{F_2}=0.583+0.324=0.907 \ m^3$

Total length C = 3 x 3.23 + 2.43 + 2.73 + 5.23 + 2 x 3.83 + 4.13 x 2 + 5.93 + 4.33 + 2.93 + 2 x 5.23 +2 x 3.83 + 3 x 3.13 + 2 x 1.23 + 1.43 = 80.59m

No. of T junction = 16

Step 2:
