• Surface area and volume for square and rectangular prisms Square prism: Rectangular prism: Surface area: Surface area: Volume: Volume:
• Surface area and volume for cones and spheres Right cone: Sphere: Surface area: Volume: Surface area: Volume:
• The effect of multiplying by a factor of k Multiplying one or more dimensions of a prism or cylinder by a constant k affects the surface area and volume of the object.
