How Many Lateral Faces Does A Triangular Prism Have?

thank you, I got it!

You're welcome. :-)

A triangular prism is a three-dimensional shape that consists of two triangular bases and three rectangular lateral faces connecting the corresponding sides of the bases. To find out how many lateral faces a triangular prism has, we can count the number of rectangular faces.

To visualize this, imagine a triangular prism. Picture a triangle as the base, and then attach three rectangles to each of the three sides of the triangle. These rectangles form the lateral faces of the prism.

Since a triangular prism has three rectangles as its lateral faces, the answer is 3.
