When a section of cylindrical wood is cut into a largest cone, its volume is reduced by 18.84 cubic decimeters
Set the bottom area as S
Cone volume: V1 = s * 3 / 3 = s
Cylinder volume: V2 = s * 3 = 3S
Cylinder volume conic volume = 18.84
V2-V1=18.84
3S-S=18.84
S=9.42
The bottom area of the column is 9.42 square decimeters
