Question 11.

The figure given above contains the following 2-Dimensional shapes.

Only triangles
Only rectangles
Both rectangle and triangle
None of these

Discuss Question

Answer: Option C. -> Both rectangle and triangle
:
C

In the figure, ABC, BCD, CDE and ACE are triangles and ABDE is a rectangle. Hence, it contains both rectangle and triangles.

Question 12. The number of edges in a match-box is ___.

Discuss Question

:
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.

Question 13. Square prism is also known as__________.

Only Cube
Only Cuboid
Either Cuboid or Cube
Pyramid

Discuss Question

Answer: Option C. -> Either Cuboid or Cube
:
C
A square prism has square oppposite faces and either rectangular or square lateral faces. Hence, it is also known as either cuboid or cube.

Question 14. A prism standing on its base will always have same top and bottom views.

True
False
Sphere
Pyramid

Discuss Question

Answer: Option A. -> True
:
A
The two bases of a prism are its two congruent opposite faces. Hence, aprism standing on its base will always have thesame top and bottom views. In the following prismstanding on its base,

A Prism Standing On Its Base Will Always Have Same Top And B...

the top view and the bottom view will be the same, which is the following:

Question 15.

Identify the front view of the figure shown above.

Discuss Question

Answer: Option A. -> True
:
A
Front view

Question 16.

Front view of the above shown solid figure is__________.

Discuss Question

Answer: Option A. -> True
:
A
Front view of the given figure is shown below.

Question 17. How many edges are there for a prism with hexagonal base?

Discuss Question

Answer: Option D. -> 18
:
D

How Many Edges Are There For A Prism With Hexagonal Base?

Here, the edges are AB, BC, CD, DE, EF, AF, AG, FL, EK, DJ, CI, BH, GH, HI, IJ, JK, KL and GL.
Hence, the number of edges are 18.

Question 18. Which among the figures is not a convex polyhedron?

Discuss Question

Answer: Option D. -> 18
:
B

Which Among The Figures Is Not A Convex Polyhedron?

This figure is not a convex polyhedron. Apolyhedronis said to beconvexif its surface (comprising its faces, edges and vertices) does not intersect itself and the line segment joining any two points of the polyhedronis contained in the interior or surface.

Question 19. A pyramid is a polyhedron whose base is a polygon and whose lateral faces are triangles with a common vertex.

True
False

Discuss Question

Answer: Option A. -> True
:
A

As you can see in the image above, apyramid is a polyhedron whose base is a polygon and whose lateral faces are triangles with a common vertex.

Question 20. Which shape among the following does not have edges?

Triangular pyramid
Rectangular prism
Sphere
Pentagon

Discuss Question

Answer: Option C. -> Sphere
:
C
An edge is a line joining the vertices. Among the four given options, a sphere has a curved surface and has no vertex. So, a sphere does not have any edges.
