Transcript of Finding Surface Area Math 6. Objectives 1- Represent three-dimensional figures using nets made up of...
Objectives
1- Represent three-dimensional figures using nets made up of rectangles and triangles, and use the nets to find the surface area of these figures.
2- Apply these techniques in the context of solving real-world and mathematical problems.
Geometric Shapes
Polygons
1. Plane (flat) closed figures.
2. Sides are line segments.
Polyhedra (Polyhedrons)
1. solid figures(3-dimensional)
2. Sides are called faces.
3. Edges are line segments
We can describe nets and their solids by the number of:
edges
vertices
faces.
Solids include rectangular and triangular prisms

Conclusion1. Surface Area of a solid means the
amount of space on the surface.
2. It is a measure of area, thus the units are square units.
3. We can find surface area of prisms and pyramids by finding the area of each face and adding.
4. A net can be helpful to use.
