How to learn amount of objects in selected prefabs folder?

Hello i want to know how many GameObjects in Source/Prefabs/Tetris but tetrisBlocks value is 0 or null? i guess cause im getting ~IndexOutOfRangeException: Index was outside the bounds of the array. tetrisGameController.GetRandomTetrisBlock () i searched on google but couldn't come up with solution.

Question: How many objects in Source/Prefabs/Tetris how can i learn?

 string GetRandomTetrisBlock()
     {
         GameObject[] tetrisBlocks = GameObject.FindGameObjectsWithTag("TetrisBlock");
         int randomTetrisBlockGenerator = Random.Range(1, (tetrisBlocks.Length));
         string[] tetrisBlockArray = new string[tetrisBlocks.Length];
         for (int i = 0; i < tetrisBlocks.Length; i++)
         {
             tetrisBlockArray[i] = "Prefab/Tetrsi/Tetris_" +i;
         }
         return tetrisBlockArray[randomTetrisBlockGenerator - 1];
     }
