F=(Fx*Fx +fyxFy)^0,5 497761.59

F= 497761.59 Newton

Force in Kg 49776.159

Density of concrete 2400 kg/cum

Volume of concrete required 20.74 cum

Keeping depth as 2 mt

Area required 10.37 sqmt

Size required considering square block 3.22 mt

Hence provide size in plan as 3.5 (Input Data)

Check for net volume after pipe diameter

Total volume 24.5

Less pipe volume'3,75*,785*1,1*1,1 3.324 cum

Net volume 21.18 cum

Volume required 20.74 cum

HENCE OK

Note: Add some extra length to get net required volume after deduction of pipe
