### Estimating Arc Length Using Simpson's Rule

#### Introduction
Simpson's Rule is a numerical method that can provide an estimated solution for the definite integral of a function. It is particularly used when an analytical solution is difficult or impossible to determine. This problem involves estimating the arc length of a given curve using Simpson's Rule.

#### Problem Statement
You are given the function \( y = \ln(1 + x^3) \) over the interval \( 0 \leq x \leq 5 \). The task requires using Simpson's Rule with \( n = 10 \) to estimate the arc length of the curve.

#### Steps
1. **Function Definition:**
   \[
   y = \ln(1 + x^3)
   \]
   with the interval \( 0 \leq x \leq 5 \).

2. **Using Simpson’s Rule:**
   Use \( n = 10 \) to estimate the arc length.

3. **Compare with Computational Tools:**
   Find the answer produced by a graphing calculator or computer and round your answer to six decimal places for both the Simpson's Rule estimate and the computational result.

#### Detailed Solution
1. **Applying Simpson's Rule:**
   Simpson's Rule requires dividing the interval into \( n \) subintervals of equal width.

2. **Arc Length Formula:**
   The arc length \( L \) of the curve \( y = f(x) \) from \( x = a \) to \( x = b \) can be approximated using Simpson's Rule in the following manner:
   \[
   L \approx \frac{\Delta x}{3} \left( f(a) + 4f(a+\Delta x) + 2f(a+2\Delta x) + \ldots + 4f(b-\Delta x) + f(b) \right)
   \]
   Here, \( \Delta x = \frac{b - a}{n} \). In this case, \( a = 0 \), \( b = 5 \), and \( n = 10 \).

3. **Graphing Calculator or Computer Estimate:**
   Compare this result with a more precise value obtained via a graphing calculator or computer software.

#### Answer Fields
- **Simpson's Rule Estimation:**
  \[
  \text{(Rounded to six decimal places)}
  \]
