Free Visualising Solid Shapes 01 Practice Test - 8th Grade
Question 1
Which are prisms among the following?
Nail
Unsharpened pencil
A box
A table calendar
SOLUTION
Solution : B, C, and D
A prism is a solid geometric figure whose two ends are congruent and parallel rectilinear figures and whose sides are parallelograms.
Usually unsharpened pencil has two hexagonal ends and six lateral faces. A box has two rectangular ends and four lateral faces. A table calendar has two triangular ends and three lateral faces. So, these three are examples of the prism.
Question 2
The given figure consists of a cylindrical part and a conical part.
True
False
SOLUTION
Solution : A
Yes, It consists of both cylinder and cone as is shown in the figure. The cone is at the top of the cylinder.
Question 3
The figure given above contains the following 2-Dimensional shapes.
Only triangles
Only rectangles
Both rectangle and triangle
None of these
SOLUTION
Solution : C
In the figure, ABC, BCD, CDE and ACE are triangles and ABDE is a rectangle. Hence, it contains both rectangle and triangles.
Question 4
Which of the following is an example of Non-polyhedron?
Cube
Sphere
Cuboid
Pyramid
SOLUTION
Solution : B
A polyhedron is a 3-dimensional solid made of polygonal faces. Spheres do not have any polygonal face, and hence are not polyhedrons.
Question 5
A prism is a polyhedron whose base and top are different polygons and whose lateral faces are parallelograms in shape.
True
False
SOLUTION
Solution : B
It should be noted that the top and the bottom of a prism are congruent while in the statement above they are mentioned to be different.
Hence the statement is false.
Question 6
Unlike plane figures, solid figures occupy
SOLUTION
Solution :Plane shapes have only two dimensions, while a solid object has three dimensions and hence occupy space.
Question 7
A person bought an ice cream cone shown in the above figure. His son looks at the top view of the ice cream cone. Which 2-D figure will his son see?
Circle
Rectangle
Square
Line
SOLUTION
Solution : A
The base of any cone is circular in shape. Hence, the top view of an ice cream cone is circular.
Question 8
Which of the folowing is the right side view of the figure shown above.
SOLUTION
Solution : C
Right side view of the shown figure is
Question 9
Identify a dice if its front, top and side views are as shown in the figure.
SOLUTION
Solution : D
If we arrange the side, top and front views together, the dice should look like
Question 10
The number of edges in a match-box is
SOLUTION
Solution :Match-box is in the form of a cuboid. So, the number of edges in a match-box is the same as the number of edges in a cuboid, which is 12. So, there are 12 edges in a match-box.
