Space Figures - 3 dimensional geometrical objects.
Also called solids.
Each has edges, faces, and vertices.
lateral face
lateral edge
vertex
Prism - 2 parallel bases that are congruent polygons. Lateral faces are parallelograms.
The type of prism is determined by the shape of its base.
Pyramid - polygon base, lateral faces are triangles.

Cylinder - 2 parallel bases that are congruent circles. Cone - Has 1 circular base and a vertex.
Net - what the figure would look like if it were "unfolded." These are 2 dimensional representations of the 3 dimensional figures.
Essential skill: You must be able to identify the shape given the net, or know what the net would look like for a given figure.

Surface area - combined area of each of the faces of the figure
Can be calculated using the figure or the net.

Make sure you are comfortable doing both!
Show all work!
What's the lateral (flat) shape of the side of the cylinder?
How can you find the length of the rectangle?
