You should be able to attain this trophy when playing the story of the game through natural progression, however, if you are looking to get this trophy earlier, I would recommend the first level in which bombs are introduced, level 9. Destroy 3 of the blocks with the bombs provided at the start of the level and then restart from the pause menu. Rinse and repeat. Note that the trophy won't unlock until you have completed, failed or restarted the level, however, if you are continuously restarting the level following the destruction of the blocks, this shouldn't be an issue.
