A pencil holder is shaped like a triangular prism. the height is 12 cm. and the width is 7. what is the lateral surface area?

Answer 1

To calculate the lateral surface area of a triangular prism, you need to find the perimeter of the base and multiply it by the height.

Since the triangular prism has a triangular base, we need to calculate the perimeter of the base triangle.

To find the perimeter of the triangle, we need to sum the lengths of all three sides.

However, the width of the triangular prism is not enough information to calculate the perimeter of the triangle or the lateral surface area.

If you can provide the lengths of all three sides of the triangular base, I can help you calculate the lateral surface area.
