To create a triangular prism with the given dimensions, you would follow these steps:

1. Start with a triangular base: Draw a triangle with a base of 6 units and a height of 6 units.

2. Extend the sides: Extend each side of the triangle vertically by 15 units. This will create three vertical edges.

3. Connect the corresponding lines: Connect the corresponding endpoints of the extensions from step 2 to create the top triangle. This will form the top face of the triangular prism.

4. Connect the corresponding line segments: Connect the corresponding line segments from the bottom triangle to the top triangle, creating three rectangular faces.

5. Complete the prism: Connect the remaining sides of the rectangles to form the three remaining faces of the prism.

Now, you have created a triangular prism with a triangular base of 6 units by 6 units and a height of 15 units.
