6th Grade Intro to Ntes

• Faces: flat sides

• Edges: lines in between 2 faces

• Vertices: corners or points where edges connect

Prisms and Pyramids

• TWO parallel bases

• Rectangular faces

• Names come from the bases

• Example: The triangular prism has two triangle bases

• 1 base

• Triangular faces

• Names come from the bases

• Example: The square pyramid has one square base

• Nets are the unfolded version of a 3d figure.

• A net shows you all the different faces and base(s)

• We can use nets to help us calculate surface area

• Total Surface Area is the area of all the sides of the 3D figure, including the bases.

• Lateral Surface Area DOES NOT include the bases.
