volume of sand taken out of the tank
=30×20×12
7200m^3

area of the field =1500m^2
since there is a digging in the middle of area
30×12
360m^2 has to be reduced from total area

new area =1500-360
=1140m2
considering uniform distribution of sand
distributing 7200m^3 sand over 1140m^2
there will be a raise of

7200/1140 m
= 6.31m
