Answer 2

Answer: 8 cubes

Step-by-step explanation:

• Tushar has to make a block with the help of minimum number of cubes.
• The required block could be made by fixing together the cubes without the cental piece.
• So,total number of cubes required =(3*3)-1

                                                                     =9-1

                                                                     =8 cubes.

• Hence,the total number of cubes required is 8.
