14. As shown in the figure, there are four shapes made up of six different building blocks. The six blocks represent six different single-digit numbers. Three blocks forming a shape represent a three-digit number. 523, 426, 376 correspond to the first three figures below (note: they may not correspond in order, i.e., 523 does not necessarily correspond to the first figure). What number does the fourth figure represent? $\qquad$

Answer: 325
Explanation: The three given numbers are $523, 426, 376$. The tens place has two identical 2s, and the units place has two identical 6s. From the first three figures, the vertical "one" shaped block represents the number 6; the horizontal "L" shaped block represents the number 2. Therefore, the first figure represents 426, the second figure represents 376, and the third figure represents 523. So, the fourth figure represents 325.
