6. The first known step pyramid was built near Saqqarah, Egypt, for
King Zoser around 2650 B.C. Three of Egypt’s largest pyramids
are found at Giza near Cairo. The largest of these, the Great
Pyramid or Pyramid of Khufu, was originally 481 feet tall and
covered about 13 acres. Another of the largest pyramids in the
world is the pyramid of Cholula, Mexico built by the Toltec
Indians. The pyramid shape is often used in the roof lines of
modern structures. Ask pupils to describe any structure they have
seen that incorporate pyramid shapes.

Answer the following questions.
1. What do you call the figures that are not flat?
______________
2. What is a three-dimensional figure with flat
surfaces? ____________
3. What is each face made of? _____________
4. What is a prism? ______________
5. What is the difference between prism and
pyramid? ____________
8. Prism - a solid geometric figure whose two end faces are
similar, equal, and parallel rectilinear figures, and whose
sides are parallelograms.
Pyramid – a polyhedron having for its base a polygon and
for faces triangles with common vertex.
9. Elements of a Prism
A prism can be labeled with its features,
which helps characterize them.
Edge: A straight line that connects any two
adjacent vertices of a prism is called its
edge.
Vertex: The corners of a prism where any
two edges meet are called vertices.
Face: It is a closed, flat surface surrounded
10. Visualizing Solid Figures
Plane Figures are two-
dimensional shapes and
they look flat. They can
be made of straight
lines, curved lines, or
both.

What is a plane figure?
A plane figure is two dimensional figure which
possesses an area but the volume of this figure is zero.
The examples of plane figures are square, circle,
rectangle, triangle etc.
Plane figures can be drawn on a paper.
The unit of area of a plane figure is square of unit of
length.
The study of plane figures is called plane geometry.”
What are the different plane figures present in the
classroom?

What is a solid figure?
Solid figures are three-dimensional objects,
meaning they have length, width, and height.
Because they have three dimensions, they
have depth and take up space in our universe.
Solid figures are identified according to the
features that are unique to each type of solid.
Specifically, you can observe the numbers of
faces, edges, and vertices, as well as the
shape of the base.
13. 13
“The three-dimensional figures are called
solid figures. These figures have an surface
area as well as a volume. These figures
cannot be drawn on a paper. The examples
of solid figures are cuboid, parallelepiped,
football, solid sphere etc. The unit of area of
a solid figure is square of unit of length.
Similarly, the volume of three-dimensional
figure is cube of unit of length.”
14. 14
A solid figure that has all flat surfaces is a
polyhedron.
Each surface of a polyhedron is a face.
Two faces of a polyhedron meet to form an edge.
The edges meet to form a vertex.
17. 17
Some solid figures are polyhedrons and some
are not.
The cube, prisms, and pyramids are
polyhedrons because they all have flat
surface.
The sphere, cylinder, and cone are not
polyhedrons because they have some
curved surfaces.

and vertices of the solid figures.
