        Calculations in the post by @mananth are incorrect.

        I came to bring a correct solution.



A trench 5m x 16m and 0.75m deep is dug.
Volume of Trench = 5*16*0.75 = 60 m^3
The earth taken out is spread uniformly to form a layer 12.5cm
deep and 4m wide. (cuboid)
4*0.125*L = 60 m^3
L = 60/(4*0.125)
length = 120 m   &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<<<---===  &nbsp;&nbsp;&nbsp;&nbsp;<U>ANSWER</U>


Solved correctly.
