G.13 - Surface Area and Volume
G.13 The student will use surface area and volume of three-dimensional objects to solve practical problems.
- I can order the square feet of canvas required to make a
tent, determine how many jelly beans fill a canister, figure how much paint
will cover walls, ceiling and floor of a room, and know how much water will fill
a fish aquarium.
- I will be
able to determine when volume and surface area are appropriate for various
UNDERSTANDING THE STANDARD
· The surface area of a cylinder, cone, or hemisphere is the sum of the areas of the curved surface and bases.
· The surface area of a sphere is the area of the curved surface.
· The lateral area of a cylinder is the area of the curved surface of the cylinder, not including the parallel bases.
· The lateral area of a rectangular-based prism is the sum of the areas of all faces, not including the parallel bases.
· The lateral area of a triangular-based prism is the sum of the areas of all faces, not including the triangular-shaped, parallel bases.
· The volume of a three-dimensional figure is the number of unit cubes that would fill the figure.
· Composite figures consist of two or more three-dimensional figures. The surface area of a composite figure may not be equal to the sum of the surface areas of the individual figures.
· Volume and surface area of spheres, cones and cylinders should be considered in terms of p or as a decimal approximation.· Calculators may be used to determine decimal approximations for results.
The student will use problem solving, mathematical communication, mathematical reasoning, connections, and representations to
