### Volume Calculation of a Triangular Prism

**Problem Statement:**
Here is a triangular prism with the following dimensions:
- Side of the triangle: 6 inches
- Side of the triangle: 8 inches
- Hypotenuse of the triangle (Base 1): 10 inches
- Height of the prism: 12 inches

**Question:**
What is the volume of the prism, in cubic inches?

**Diagram Explanation:**
The diagram showcases a triangular prism with given dimensions. The front face of the prism is labeled as a right triangle with sides measuring 6 inches and 8 inches. The hypotenuse (the longest side) is 10 inches. The prism extends to a height (or length) of 12 inches.

**Solution:**

1. **Determine the Area of the Triangular Base:**
   The base of the triangular face is a right triangle. The area of a right triangle is calculated using the formula:
   \[
   \text{Area} = \frac{1}{2} \times \text{base 1} \times \text{base 2}
   \]
   Substituting the given values:
   \[
   \text{Area} = \frac{1}{2} \times 6 \times 8 = 24 \text{ square inches}
   \]

2. **Calculate the Volume of the Prism:**
   The volume of a prism is found by multiplying the area of the base by the height (length) of the prism:
   \[
   \text{Volume} = \text{Base Area} \times \text{Height}
   \]
   Using the given height of 12 inches:
   \[
   \text{Volume} = 24 \times 12 = 288 \text{ cubic inches}
   \]

**Answer:**
The volume of the prism is 288 cubic inches.

This explanation and solution should provide a clear understanding of how to approach and solve problems involving the volume of a triangular prism.
