|---|---|
| a polyhedron with exactly two congruent, parallel faces | prism |
| the congruent, parallel faces of a prism | bases |
| the faces of a prism that are not the bases | lateral faces |
| a perpendicular segment that joins the planes of the bases | altitude |
| the length of the altitude | height |
| sum of the areas of the lateral faces | lateral area |
| sum the of the lateral area and the area of the two bases. | surface area |
