Dongju selects a piece of paper with a number written on it, and wants to make a three-digit number by placing the first selected number in the hundreds place, the second selected in the tens place, and the third selected in the units place. If the numbers written on each paper was 1, 6, and 8, respectively, find the sum of the second smallest and third smallest three-digit numbers that Dongju can make. However, you cannot select the same numbered paper multiple times.
