G 405. Use geometric formulas when all necessary information is given
G 601. Use relationships involving area, perimeter, and volume of geometric figures to compute another measure (e.g., surface area for a cube of a given volume and simple geometric probability)
G 602. Use the Pythagorean theorem
G 705. Solve multistep geometry problems that involve integrating concepts, planning, and/or visualization

What you'll learn
- Find the surface area of a prism, cylinder, pyramid, cone or sphere: determine whether the problem asks for lateral or total surface area, choose the formula that fits the solid, and add the right number of bases
- Compute the surface area of right prisms (rectangular, triangular) and cylinders using LSA = Ph and TSA = LSA + 2B
- Compute the surface area of regular pyramids and cones using LSA = 1/2 Pl and LSA = pirl, finding the slant height by the Pythagorean theorem when only the height is given, and find TSA by adding the base area
- Apply the sphere formula SA = 4pir^2 (no LSA/TSA distinction)
