2 A three-dimensional figure has a: length, width and height.
A face is any of the flat surfaces on a three-dimensional figure. A prism is a 3D figure with two parallel and congruent polygonal bases. A pyramid has only ONE base and a vertex at the top where the edges meet. The height is the distance between a prism’s bases.

3 First Try Using the figures at your tables, try to draw what they would look like if they were unfolded and laid flat.

4 Construct Nets of the Solids
Second Try- Draw the actual net. How close was your first try? Rectangular Prism: Know this: The net of a rectangular prism can look many different ways… but it should ALWAYS contain 6 rectangles. Think about how different these boxes would all look unfolded even though they all are rectangular prisms.

5 Other nets of a rectangular prism

6 Gold Tower in Utazu, Japan
Construct nets of the Solids Know this: The net of a triangular prism can look many different ways… but it should ALWAYS contain 2 triangles and 3 rectangles. Second Try- Draw the actual net. How close was your first try? Triangular Prism: Flat Iron Building, NYC Gold Tower in Utazu, Japan

7 Other nets of a triangular prism
Think about how different these boxes would all look unfolded even though they all are triangular prisms.

8 Construct nets of the Solids
Second Try- Draw the actual net. How close was your first try? Rectangular Pyramid: Again.. The net of a rectangular pyramid can look many different ways… but it should ALWAYS contain 1 rectangle (or square) and 4 triangles.

9 Other nets of a rectangular pyramid
Think about how different these boxes would all look unfolded even though they both are rectangular pyramids.

10 Construct nets of the Solids
Second Try- Draw the actual net. How close was your first try? Triangular Pyramid: Again.. The net of a triangular pyramid can look many different ways… but it should ALWAYS contain 4 triangles.

11 Other nets of a triangular pyramid

12 Construct nets of the Solids
Second Try- Draw the actual net. How close was your first try? Cube: Know this: The net of a cube may be different sizes… but it should ALWAYS contain 6 squares.

13 There are altogether 11 possible nets for a cube as shown here:
Other nets of a cube There are altogether 11 possible nets for a cube as shown here:

14 Other nets …. What would these look like?

15 Identifying the Faces and Bases
A prism has at least two congruent (same size and shape) faces that are parallel to one another. These parallel faces are called bases of the prism, and are often associated with its top and bottom. Solid Number of faces List the polygons that make up solid figure. Shape of Base Cube  6 Six squares. Square Rectangular Prism Six rectangles. Rectangle Triangular Prism 5 Three rectangles and two triangles. Triangle Rectangular Pyramid Four triangles and one rectangle. Triangular Pyramid 4 Four triangles.

16 Personal Ad Activity You will choose one of the 5 polyhedrons (rectangular prism, cube, triangular prism, triangular pyramid, or rectangular pyramid) and write a personal ad for the polyhedron. The “ad” should describe the attributes of the polyhedron you chose. (Be sure to draw a picture as well..) See examples on next page (not polyhedrons.)

17 Personal Ad “I’m short, pudgy with bright blue eyes. I love to cook and am extremely adorable. I’m a big softy with lots of dough and laughs. Very ticklish.” Poppin’ Fresh

18 Personal Ad “Born in Kentucky. I’m tall and often bearded. A self-taught lawyer and accomplished wrestler. I yearn for peace and freedom for all. Well-spoken and intelligent.” Abe Lincoln
