Surface Area & Volume

Video Tutorials

Surface Area of Rectangular Prisms and Square Pyramids

Surface Area of Triangular Prisms

Surface Area of a Regular (Equilateral) Triangular Pyramid

Surface Area of a Cylinder (the long way, but it's good to know how to do it this way. It will help you to better understand the formula.)

Finding the Formula for Surface Area of a Cylinder: 2𝜋r2 + 2𝜋rh (she takes the formula one step further by factoring out 2𝜋r )

Surface Area of a Cylinder: Examples Using the Formula (She also does a volume problem, which you may find interesting, but you won't be responsible for knowing that until Math 8).
