1
Identify each of the following shapes. In geometry, what is a net? what is surface area? cube Triangular pyramid Right square pyramid Rectangular prism cylinder

2
Net Surface Area A flat representation of all the faces of a polyhedron Sum of the areas of its faces

3
9.1 Solid Figures 3-D shapes are solid figures or solids

4
A solid with faces that are polygons (a closed plane figure with at least three sides) polyhedron face The polygons that make up a polyhedron are the faces of the polyhedron. A solid that is formed by polygons

5
A polyhedron with two congruent and parallel faces, called bases. The other faces, which are parallelograms, are the lateral faces. Prisms

6
Rectangular Prism Prism is rectangular because the bases are congruent rectangles. Lateral edges are perpendicular to the bases.

7
