volume of rectangular area=volume of cubic stone
40m.12m .h=120m^3
=> h=1/4m=25cm
hence deep 25cm
40m.12m .h=120m^3
=> h=1/4m=25cm
hence deep 25cm

Answer:
VOLUME =AREA OF THE RECTANGULAR SURFACE × HEIGHT
VOLUME = L×B×H
⇒120=40×12×H
⇒120/40×12=H
⇒1/4=H
⇒0.25m=H
THEY WILL BE 0.25m DEEP
hope this helps
