How to add Excel WorkBook on your site.? For some the answer to the question may be very simple. Go to Scribd and Upload... But the main problem exists when you add the word interactive to your question. I searched my net hoping to find the answer. But the articles on the net were not useful and were very old. So, I decided to write a guide to help you.

Go to the following link.

Login through your Microsoft account. Click "Upload" (3rd button from top-left).

Now Upload the Desired File.

After the desired file appears, Right Click it and Click Embed.

Click "Customise how..."

In interaction group, check the 2nd option.
Copy the code in "Enbed Code".

Open Blogger and Click New Post, then click on HTML Tab.

Paste the Copied Code and Publish the Post and see your Excel Workbook added to your blog.

And now Compare it with Scribd method

Age of Mythology: Solution: "Insert the Age of Mythology CD" error

Well the earlier night while playing one of my favorite games Age of Mythology, I encountered an error. It read "Insert the Age of Mythology CD".

*Well you can only solve the error if you are not playing the game by CD ROM but instead it is on your PC.

  1. Download the file from here.
  2. Extract the the downloaded zip file.
  3. Now right-click the icon on the desktop and click Open File Location.

Presentation on Surface Area and Volumes Grade 9/10

Surface Area and Volumes
By – XYZ
Subject – Maths, Sub. Teacher  - Ms. XYZ
XYZ School,

Surface Area & Volume Defination
Surface area is the total area of the faces and curved surface of a solid figure.
Volume is the quantity of three-dimensional space enclosed by some closed boundary.

Right Circular Hollow Cylinder
Right Circular Cone
Spherical Shell
Hemispherical Shell
Frustum of a Right Circular Cone

A closed figure whose faces are rectangles, is called a cuboid.
Let l, b and h are respectively the length, breadth and height of a cuboid, then.
Volume = lbh cubic units
Total Surface Area of a Cuboid = 2(lb + bh + hl) sq. units.
Lateral Surface Area = 2(l + b)h sq. units.
Diagonal = √l2 + b2 + h2 units.

When all sides (edges) of a cuboid are equal in length, it is called a cube.
If length of each egde of a cube is a units, then
Volume = a3 cubic units.
Total Surface Area = 6a2 sq. units.
Lateral Surface Area = 4a2 sq. units.
Diagonal = √3 a units.

A right circular cylinder is a solid generated by the revolution of a rectangle about one of its sides.
Let r be the radius and h be the height of a cylinder. Then,
Volume = πrh
             = Area of base x height
Curved Surface Area  = 2πrh
                                    = Perimeter of the base x height
Total Surface Area      = Curved Surface Area + Area of both circular ends
                                    = 2πrh + 2πr²
                                    = 2πr (h +r)
Area of each end         = πr²

Right Circular Hollow Cylinder
Let r and R be the internal and exterior radii of a hollow cylinder of height h, Then,
Area of each end             = πR²-πr²= π(R²- r²)
Curved Surface Area      = Inner Curved Surface Area +  Outer Curved Surface Area
                                        = 2πrh + 2πRh
                                        = 2πh (r+R)
Total Surface Area          = Curved Surface Area + Area of                                                                  both ends
                                         = 2πrh + 2πRh + πR²-πr² + πR²- πr²

                                         = 2πh (r+R) + 2π(R²- r²)
                                         = 2πh (r+R) + 2π(R+r)(R-r)
                                         = 2π(r+R)(h+R-r)
Volume of material
                                         = External Volume – Internal Volume
                                         = πR²h-πr²h
                                         = πh(R²-r²)

Right Circular Cone
If a right angle triangle is revolved about one of the sides containing the right angle, the solid thus generated is called a right circular cone.
If r, h and l be the radius, height and slant height of the cone, then
l = √r² + h², r = √l² - h², h = √ l² - r²
Curved Surface Area      = πrl
Total Surface Area          = Curved Surface Area + Area of base
                                        = πrl + πr²
                                        = πr(l +r)
Volume                            = (1/3)πr²h
                                        = (1/3)(Area of base) x height

It is the locus of a point in space, which moves such that its distance from a fixed point is always constant.
If r be the radius of sphere, then
Surface Area                  = 4πr²
Volume                           = (4/3)πr³
For Hemisphere
Surface Area                  = 4πr²
Total Surface Area        = 2πr² + πr² = 3πr²
Volume                          = (2/3)πr³

Spherical Shell
Let r and R be the inner and outer radii of a the sphere.
Volume of material           = (2/3)πR³ - (2/3)πr³
C.S.A. (if edge ignored) : = 2πr² + 2πR²
C.S.A. (if edge included): 2πr² + 2πR² + πR² -πr²

Frustum of Right Circular Cone
Frustum of a cone is the solid obtained after removing the upper portion of the cone by a cone parallel to its base. The lower portion thus obtained is called frustum of the cone.
If the radii of bigger and smaller bases of the frustum are ‘R’ and ‘r’ slant height be ‘l’ then
Slant height (l)             = √h² + (R-r)²
Curved Surface Area   = π(R+r)l
Total Surface Area       = C.S.A. + πR² + πr²
Volume                         = (1/3)πh(R² + r² +R.r)

Mission JSTSE

Here is the complete guide which a student needs to clear JSTSE.

Self Confidence
S. Chand Book (395 Rs.), 10th Class Science Book (135 Rs.), PC and Internet (30K), Self Confidence (NA), Hard Work (NA).



Junior Science Talent Search Examination is conducted by the Directorate of Education every year. It happens mostly in late January and mostly on Sundays. Only students of class IX in Delhi can give this exam and to give this exam, you need to secure 65% in your previous class i.e. Class VIII.

The JSTS process starts in August/September where the school has to fill in a registration form and send it to the Directorate Of Education.

The first level paper is divided into 2 parts. The first part is a 1 hour GK paper which tests your knowledge of GK, current affairs etc. It is a 50 marks paper. The next level paper is a 3 hour paper that tests your Maths and Science. There are about 30 questions in Maths and 40 questions each in Physics, Chemistry and Biology. 200 marks in 180 minutes.

The first round results come out usually in mid April and are uploaded at the Directorate of Education website under public Circulars ( There were 162 students selected in the first level in 2012-13. There is no interview.


Mirror Formula
  • Mainly from 10th NCERT.
  • Main topics - Light, Electricity, Heat, Magnetic Effect of Electric Current. 
  • First study from the NCERT with proper concepts, and then try the JSTSE book.
  • Don't only mug up formulas, know their proper use. For example, If you know how to calculate equivalent resistance in an electric circuit, you should know how these formulas are derived, similarly, knowing the mirror formula won't help, you should know its proper application (sign convention) and use.

  • Chemistry in JSTSE is mostly general and is about formulas of various compounds, uses of different things, etc.
  • Requires Hard Work.
  • Thoroughly study chemistry section of GK book.
  • Concepts in 9th should be thoroughly studied.

  • GK in JSTSE is plain and can be high scoring.
  • Quite unpredictable.
  • Last year, it was mostly the History Book Chapters (9th class) and specifically the ones in SA-II.
  • Logos have been removed from the syllabus.
  • Along with your GK books you need to consider the History Book as well.
  • Difficulty level unpredictable.
  • The main topics are mostly from 9th.
  • Along with 9th and 10th Science Books, the reference book for 9th should be sufficient.
  • Needs a lot of practice.
  • S. Chand JSTSE book sufficient.

  • Study for the exam from beginning of the session.
  • Cover the syllabus before the winter vacation.
  • In the vacation,
    • Do mock tests.
    • Solve and learn questions from Previous' Years papers.
  • On the night just before the exam,
  • Mock Test.
    • Relax.
    • Have a great sleep.
  • On the exam day,
    • Be calm, composed and confident.
    • Don't interact with your classmates.
  • After the exam,
    • Enjoy.
    • Relax.
