1.125m is the embarkment

Lel: In starting it will be 99 instead of 66 as you have done 14/2=2 Instead of 7.

let the height of embankment h metre

then volume of embankment is equal to volume of earth taken out

= 22/7 ×1.5 ×1.5 ×14 = 22/7 (5^2 -1^2) h

= 2.25×14 = 24h

= 24h = 31.50

h = 1.3125 m
