Let us assume well as a solid circular cylinder

Radius of circular cylinder =2/2 = 1 m

Height (or) depth of well = 14m

Given that height of embankment (h) = 40cm

Let width of embankment be ‘x’ m

Since well is spread evenly to form embankment so their volumes will be same so equating (1) and (2)
