# 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.
