The coach placed a total of 15 tennis balls + 5 soccer balls = 20 balls in each basket.
So, there are 20 balls x 5 baskets = 100 balls in total.
3 students removed 8 balls each, so they removed a total of 3 students x 8 balls/student = 24 balls.
The other 2 students removed a total of 100 balls - 56 balls - 24 balls = 20 balls.
Each of the other 2 students removed 20 balls / 2 students = 10 balls each.
Therefore, the other 2 students each removed 10 balls.
#### 10#### 10
The answer is: 10

### Problem:
A coach placed 15 tennis balls and 5 soccer balls each into 5 baskets. He gave 5 of his students a short period of time to remove as many balls each from a basket as they could. 3 of them removed 8 balls each and the other 2 removed a certain number of balls each. If a total of 56 balls are still in the baskets, how many balls did the other 2 students each remove?
