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

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

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

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

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

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

Cylinders base height Radius
