# Free Visualising Solid Shapes 01 Practice Test - 8th Grade

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.

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.

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.

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.

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.

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.

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.

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

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

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.
