Answer: (2) 12 cm
Explanation:-
Given-

Length = 20 cm, breadth = 16 cm  & volume = 3840 cm cube
The volume of the cuboid = 3849 cm cube

Formula- 
The volume of the cuboid  = l x b x h
Where, l = length of the cuboid , b = breadth of the cuboid & h = height of the cuboid.

Then,  20 x 16 x h = 3849
h = 3849/320
h = 12 cm
Then, the length of the cuboid is 12 cm .

Hence, the answer is (2) 12 cm.
