A retaining wall 9 m high retains granular fill weighing 18 kN/m³ with level surface. The active thrust on the wall is 180 kN per meter length of the wall. The height of the wall is to be increased and to keep the force on the wall within allowable limits, the backfill in the top half of the depth is removed an replaced by cinders. If cinders are used as backfill even in the additional neight, what additional height (in m) may be allowed if the thrust on the wall s to be limited to its initial yalue?

Correctly if u know the method .Thank you
![A retaining wall 9 m high retains granular fill weighing 18 kN/m³ with level
surface. The active thrust on the wall is 180 kN per meter length of the wall.
The height of the wall is to be increased and to keep the force on the wall
within allowable limits, the backfill in the top half of the depth is removed and
replaced by cinders. If cinders are used as backfill even in the additional
height, what additional height (in m) may be allowed if the thrust on the wall
is to be limited to its initial value?
