A big cubical box is filled with small cube boxes of 1 cubic unit each.


The volume occupied by all the small cube boxes is cubic units.

The correct option is C 10
Each small cube box occupies 1 cubic unit of volume in the big cubical box.

Let's count the number of small cube boxes in the big cubical box.


Hence, 10 small cube boxes are present in the big box.

The total volume of the 10 small cube boxes is 10 cubic units.

Hence, the volume occupied by the small cube boxes is 10 cubic units.
