The base of a right prism is a right angled triangle of side 8 cm, 15 cm and 17 cm (a,b,c). Its height is 20 cm. Find the lateral surface area and the total surface area of the prism. (Note: In a right angled triangle the longest side is called as the hypotenuse. The other two sides may be taken as either as the base or the height of the triangle).
