The purpose of this lesson is to learn how to find the surface area of a solid.
This lesson will address the following CCRS Standard(s) for Geometry:
- 7.G.6: Solve real-world and mathematical problems involving area, volume and surface area of two- and three- dimensional objects composed of triangles, quadrilaterals, polygons, cubes, and right prisms
- Take notes while watching videos below

In this lesson we have learned:
- If P is the perimeter of the base of a prism (or circumference of the base of a cylinder), and B is the area of the base, then the surface area of the prism (or cylinder) is (where l is the slant height)
- If P is the perimeter of the base of a pyramid (or circumference of the base of a cone), and B is the area of the base, then the surface area of the pyramid (or cone) is (where l is the slant height)
