A circular drum here means that its a cylinder geometrically, right?
You must know the formula of the volume of cylinder
V = 4πr²h... Find the volume of cylinder using this formula and given values of radius and height. (V = 1086.18 m³)
Its also given that each bag occupies 1.8 m³ of volume
Now just assume that there will be x bags that can occupy the entire drum, so both their volumes must be the same, right?
x*1.8 = 1086.18
x = 1086.18/1.8
x = 603.43. Now this isn't possible because no of bags cannot be a fraction, can it?
So, x = 603 bags.
Godspeed!!
