Lesson 60 Geometric Solids

• A geometric solid is a geometric figure that has
  three dimensions.
• A prism is a geometric solid where two faces
  (called bases) are identical and parallel and
  where the other faces are parallelograms (called
  lateral faces).
• A cylinder is like a prism except that its bases
  are closed curves instead of polygons. The curved
  surface between the bases is called the lateral
  surface.

• Ex. 60.1 The area of the base of a right
  pentagonal prism is 28 cm squared and the length
  of the lateral edge is 10cm. Find the volume.
• EX. 60. 2 find the lateral surface area of a
  right pentagonal prism. The length of a lateral
  edge is 15m and a side of the pentagon is 5m.
