In how many ways can 30 balls of 10 different colors, 3 identical pieces of each color, be randomly distributed in 10 similar boxes?

To solve this problem, we need to determine the number of ways to distribute 30 balls of 10 different colors (with 3 identical balls of each color) into 10 identical boxes. Since the boxes are identical, this is a problem of partitioning the balls into non-distinguishable groups.

### Problem Breakdown:

1. **Balls Distribution**: We have 30 balls, with 3 balls of each of the 10 colors.
2. **Boxes are identical**: The boxes are indistinguishable, so we are interested in counting the distinct partitions of these balls among the boxes.

### Step-by-Step Solution:

This is a classic combinatorial problem that can be solved using the **Polya Enumeration Theorem** or by recognizing it as a problem of partitioning multisets into identical boxes.

However, given the specific constraints (10 different colors with 3 identical balls of each color and 10 identical boxes), we can approach this problem using the following reasoning:

#### Step 1: Partitions of the 30 Balls
We need to count the number of ways to partition 30 balls into up to 10 groups where each group corresponds to a box and groups can be empty.

#### Step 2: Generating Function
The problem can be interpreted as finding the coefficient of \( x^{30} \) in the expansion of:
\[
\prod_{k=0}^{10} \frac{1}{1 - x^k} \quad \text{where } k \text{ ranges over the possible numbers of balls in a box.}
\]
However, this calculation involves partition functions and would require a computational approach for exact enumeration.

#### Step 3: Consider the Complexity
Given the complexity of exact enumeration, in many contexts, this is approximated or calculated using computational methods, which is beyond manual calculation but can be tackled using partition function algorithms or generating functions implemented in mathematical software.

### Simplified Approximation/Answer:
For practical cases, if you're looking for a general combinatorial counting answer without deep computational methods, this problem requires advanced combinatorial tools. As such, without using software, it's challenging to provide an exact number manually.

However, you can use **Burnside's Lemma** or computational tools like the Pólya Enumeration Theorem to calculate the exact number.
