Height and Diameter of the cylinder are the important dimensions here. Both are = 6
So we can kinda can imagine cubes (with edge = 6) in place of cylinders for easy picturing.

[x] = Floor function
Number of cubes possible = [18/6] * [12/6] * [20/6] = 3*2*3 = 18

First instinct was to divide the volume of the box by the volume of the cylinder but I guess it doesn't work that way cause of dimensions constraints
