**Triple Integral Evaluation over a Rectangular Prism**

**Problem Statement:**

Evaluate the triple integral:

\[
\iiint\limits_{B} (4x^3 + 3y^2 + 2x) \, dV
\]

where the region \( B \) is defined as:

\[
B = \{ (x, y, z) \mid 0 \leq x \leq 8, \, 0 \leq y \leq 8, \, 0 \leq z \leq 9 \} 
\]

**Region Description:**

The region \( B \) is a rectangular prism (cuboid) in 3-dimensional space. Its dimensions are given by the intervals on \( x \), \( y \), and \( z \):

- \( x \) ranges from 0 to 8.
- \( y \) ranges from 0 to 8.
- \( z \) ranges from 0 to 9.

The volume \( dV \) represents an infinitesimally small volume element within this region.

**Integral Explanation:**

The given integral computes the accumulation of the function \( 4x^3 + 3y^2 + 2x \) over the entire volume of the rectangular prism \( B \). This involves integrating with respect to \( z \), \( y \), and \( x \), typically in that order, although the order can vary based on the problem requirements.
