10-4 Space Figures
Base (B)-The two parallel sides of a prism
Faces - The sides (polygons) of a prism
Prism- A 3-dimensional shape with two parallel bases and
sides that are all polygons
1.) What is the shape of the
bases in this prism?
Cylinder- A three dimensional shape with two
parallel bases

Pyramid - A 3-dimensional shape with one polygon as a
base and triangular sides that meet at a vertex
Cone - A three dimensional shape with one circle as a
base and one vertex (similar to a pyramid)

Also know as a ball.
given point.
Net- A pattern you can fold into a space figure
Name the solid shape that can be made from each net.
Surface area- The total area of the surface (faces and bases) of a threedimensional figure
Lateral Area- the area of the faces of a three dimensional shape (Surface area not including
the bases)
Surface area of a Rectangular Prism
For a rectangular prism, the surface area is the sum of the areas of all 6 faces

Surface Area is the sum of the areas of all the faces of a 3-D
figure. For a triangular prism, it's the sum of the areas of the
two triangular bases (A = bh 2), and the three rectangular
sides.
