Explanation:

- To solve the problem, start by calculating the volume of the cuboid: multiply its dimensions. The volume is 9 cm x 12 cm x 15 cm = 1,620 cubic centimeters.

- Calculate the volume of one small cube with a side of 3 cm: 3 cm x 3 cm x 3 cm = 27 cubic centimeters.

- Divide the cuboid's volume by the small cube's volume to find how many cubes can be formed: 1,620 ÷ 27 = 60.

- Therefore, 60 identical small cubes of 3 cm can be formed from the cuboid.

- Option 3: 60 is the correct answer.
