Surface Area of Prisms and Cylinders
- Prisms: Two bases formed by congruent polygons that lie in congruent planes
- Lateral faces are not bases and are formed by parallelograms
- Lateral edges are formed by the intersection of two adjacent lateral faces
- The altitude measures the height of the prism
- Right prism: A prism whose lateral edges are also altitudes
- Oblique prism: A prism that is not right
- Lateral area: The area of all the lateral faces of a prism
- Surface area of a prism: The sum of the areas of its outer surfaces, or lateral area + 2(area of the base)
- Cylinders have two bases that are parallel and congruent circles
- The axis is the segment whose endpoints are centers of the circle
- An altitude is a segment that measures the height
- In a right cylinder, the axis is the same as the altitude; in an oblique cylinder, the axis is not the same as the altitude
- Lateral area of a right cylinder = 2πrh
- Surface area of a right cylinder = lateral area + 2(area of the circle)
