### Geometry6.10 Lateral Surface Area of a Triangular Prism Example: Calculate the lateral surface area of a triangular prism of sides 13cm., 15cm. and 17cm. and height 25cm. Solution: Lateral surface area of the prism (A) = p * h Where p = perimeter of the base and h = height. Perimeter of the base (p)= 13 + 15 + 17 p = 45cm. h = 25cm. Therefore, A = p * h A = 45 * 25 = 1125 Sq. cm. Directions: Solve the following problems. Also write at least 5 examples of your own.
