Answer sheet
g. Square-based pyramid
GRADE 4
h. Triangle-based pyramid
Name one property for each of the above-named (a-h) 3D objects.
a. All 6 faces are equal squares.
b. Has a circle for its base and the other face connects to a point.
c. 4 faces are equal rectangles and the other 2 could be squares or rectangles.
d. An object with no faces.
e. Have circles for bases and a curved face that connects the two bases.
f. Have triangles for bases and the other three faces are triangles.
g. Has a square for its base and four triangles for the other faces.
h. Has a triangle for a base and three more triangles for the faces.
Write an example of where you will find the following:
Cube: Boxes, note paper container, etc.
Cone: Ice cream cone, cones on the soccer or rugby field to practice with, etc.
Square-based pyramid: Perfume container, Egyptian Pyramids, etc.
Cylinder: Cup, containers, bottles, etc.
Sphere: Netball ball, soccer ball, cricket ball, planet Earth, etc.
What is the difference between a prism and a pyramid?
A prism has rectangles for all the faces that connect the two bases. A pyramid has
triangles for all the faces that connect the base with the connection point.
