**Topic: Evaluating Triple Integrals Over a Rectangular Region**

**Problem:**

Evaluate the triple integral:

\[
\iiint\limits_B (xy + yz + xz) \, dV
\]

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

\[
B = \{(x, y, z) \,|\, 0 \leq x \leq 10, \, 0 \leq y \leq 7, \, 0 \leq z \leq 1\} .
\]

**Explanation:**

This problem involves evaluating a triple integral over a specified rectangular region in three-dimensional space. The integrand is a linear combination of the product of the variables \( x \), \( y \), and \( z \).

**Steps to Solve:**

1. **Identify the limits of integration:**
   - \( x \) ranges from 0 to 10.
   - \( y \) ranges from 0 to 7.
   - \( z \) ranges from 0 to 1.

2. **Set up the integral:**
   The integral will be evaluated iteratively, typically in the order of \( dz \), \( dy \), and \( dx \), unless specified otherwise.

3. **Evaluate the inner integral first:**
   - Integrate with respect to \( z \) from 0 to 1.

4. **Evaluate the middle integral:**
   - Integrate the result with respect to \( y \) from 0 to 7.

5. **Evaluate the outer integral:**
   - Integrate the result with respect to \( x \) from 0 to 10.

By following these steps, you will obtain the value of the triple integral over the region \( B \). This is a common method for solving problems involving volume integrals in multivariable calculus and is useful in applications such as computing mass, charge, or other quantities distributed in a three-dimensional space.
