  • Area Area is the two dimensional space inside the boundary of a flat object. It is measured in square units.
  • Area continued
  • Surface area of prisms and cylinders Surface Area is the total area of the exposed or outer surfaces of a prism. A net is the unfolded “plan” of a solid. The net of a cylinder
  • Volume of prisms and cylinders Volume is the three dimensional space occupied by an object, or the contents of an object. It is measured in cubic units.
  • Pyramids, right cones and spheres A pyramid is a geometric solid that has a polygon as its base and sides that converge at a point called the apex. The sides are not perpendicular to the base.
  • 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.
