Definitions
__Altitude of a prism__- A segment that has endpoints in the planes containing the other base, which is perpendicular to both planes __height of a prism-__ is the length of an altitude VariablesS- Surface Area L- Lateral B- Base p- Perimeter h-height

Surface Area of a Right Prism
S= L+2B or S=hp+2B

**Surface Area of a Right Prism**
//The area of the base is// B= 1/2(5)(13)=13 //The perimeter of each base is// p=5+13+12=30 //So the lateral is// L=hp //The Surface Area is// S=L+2b
