Free Visualising Solid Shapes 01 Practice Test - 8th Grade 

Question 1

Which are prisms among the following?

A.

Nail

B.

Unsharpened pencil

C.

A box

D.

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.

A.

True

B.

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.

A.

Only triangles

B.

Only rectangles

C.

Both rectangle and triangle

D.

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?

A.

Cube

B.

Sphere

C.

Cuboid

D.

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.

A.

True

B.

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?

A.

Circle

B.

Rectangle

C.

Square

D.

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.

A.

B.

C.

D.

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.

A.

B.

C.

D.

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.
