a surface of a polyhedron formed by a polygon and its interior

the intersection of two faces in a polyhedron

a solid formed by polygonal surfaces that enclose a single region of space

a polygon or circle used for reference to determine a height

a point of intersection of two or more segments in a figure

Is a base a face?

Match each definition with a term on your sheet. Then identify each term on a diagram

WARM-UP

In this section we will answer…

How are solids named?

What are the parts of solids?

How do I find the volume of a rectangular prism?

Definition – a polyhedron with two faces that are congruent, parallel polygons.

The faces of the prism which are not bases are called the lateral faces.

Definition – a polyhedron which has only one base.

The point where all the lateral edges meet is called the vertex of the pyramid.

Definition – A solid which has two circularbases.

The segment which connects the centers of the bases is called the axis.

Definition – A solid which has only one circular base.

Definition – A solid that is the set of all points in space which are a specific distance from a given point, called the center.

A great circle is formed when the sphere is cut through its center forming two hemispheres.

Surface Area means

Volume means

If B is the area of the base of a right rectanglular prism and H is the height of the solid, then the formula for the volume is…
