Total Surface Area (TSA) - Total Surface Area, denoted as TSA signifies the entire expanse covered by an object's surface. This encompasses the collective area of all its external facets. Here are some prominent geometrical figures and their corresponding TSA formulas:
Cuboid: TSA = 2[(l x b) + (b x h) + (h x l)]
Cube: TSA = 6a^{2}
Right Circular Cylinder: TSA = 2πr(h + r)
Right Circular Cone: TSA = πr(l + r)
Sphere: TSA = 4πr^{2}
Right Pyramid: TSA = LSA (Lateral Surface Area) + Area of the base
Prism: TSA = LSA (Lateral Surface Area) × 2B (Area of the base)
Hemisphere: TSA = 3 × π × r^{2}
Lateral/Curved Surface Area (LSA/CSA) - The concept of Curved Surface Area (CSA) or Lateral Surface Area (LSA) comes into focus, particularly in forms such as cylinders, cones, and pyramids. CSA represents the area of the curved component or sides excluding the top and bottom facets. LSA, on the other hand, pertains to the lateral area of various shapes. The following are some key examples of these surface area measures:
Cuboid: CSA = 2h(l + b)
Cube: CSA = 4a^{2}
Right Circular Cylinder: CSA = 2πrh
Right Circular Cone: CSA = πrl
Right Pyramid: LSA = (1/2)× p × l
Prism: LSA = p × h
Hemisphere: LSA = 2 × π × r^{2}
Volume - Volume emerges as a fundamental attribute, denoting the spatial extent occupied by an object or substance, quantified in cubic units. The following volume formulas unravel the essence of these geometric measurements:
Cuboid: Volume = lbh
Cube: Volume = a^{3}
Right Circular Cylinder: Volume = πr^{2}h
Right Circular Cone: Volume = (1/3)πr^{2}h
Sphere: Volume = (4/3)πr^{3}
Right Pyramid: Volume = (1/3) × Area of the base × h
Prism: Volume = B (Area of the base) × h
Hemisphere: Volume = (2/3)× (πr^{3})

Let us assume the height of the cylinder to be h.
Since the material is melted and recast thus its volume will remain the same.
So, Volume of sphere = Volume of obtained cylinder.
Hence the height of the cylinder is 2.74 cm.
According to the question, small spheres are melted and converted into a bigger sphere. Thus the sum of their volume is equal to the volume of the bigger sphere.
The volume of 3 small spheres = Volume of bigger sphere
Let us assume the radius of the bigger sphere is r.
Hence the radius of the sphere obtained is 12 cm.
According to the question, the volume of soil dug will be equal to the volume of the platform created.
Thus we can write :
The volume of soil dug = Volume of platform
Thus the height of the platform created is 2.5 m.
According to the question, the volume is conserved here :
The volume of soil dug out = Volume of the embankment made.
Let the height of the embankment is h.
Hence the height of the embankment made is 1.125 m.
Let the number of cones that can be filled with ice cream be n.
Then we can write :
The volume of a cylinder containing ice cream = n ( volume of 1 ice cream cone )
Hence the number of cones that can be filled is 10.
Let us assume the number of coins that need to be melted be n.
Then we can write :
The volume of n coins = Volume of cuboid formed.
Thus the required number of coins is 400.
According to question volume will remain constant thus we can write :

Firstly we will calculate the volume of rainfall :
Volume of rainfall :
And the volume of the three rivers is :
It can be seen that both volumes are approximately equal to each other.
From this, we can write the values of both the radius (upper and lower) and the height of the frustum.
Thus slant height of frustum is :
Now, the area of the tin shed required :
= Area of frustum + Area of the cylinder
In the case of the frustum, we can consider:- removing a smaller cone (upper part) from a larger cone.
So the CSA of frustum becomes:- CSA of bigger cone - CSA of the smaller cone
And the total surface area of the frustum is = CSA of frustum + Area of upper circle and area of lower circle.
Similar to how we find the surface area of the frustum.
The volume of the frustum is given by-
=Volume of the bigger cone - Volume of the smaller cone

Hello Aspirant, Hope your doing great, your question was incomplete and regarding what exam your asking.
Yes, scoring above 80% in ICSE Class 10 exams typically meets the requirements to get into the Commerce stream in Class 11th under the CBSE board . Admission criteria can vary between schools, so it is advisable to check the specific requirements of the intended CBSE school. Generally, a good academic record with a score above 80% in ICSE 10th result is considered strong for such transitions.
hello Zaid,
Yes, you can apply for 12th grade as a private candidate .You will need to follow the registration process and fulfill the eligibility criteria set by CBSE for private candidates.If you haven't given the 11th grade exam ,you would be able to appear for the 12th exam directly without having passed 11th grade. you will need to give certain tests in the school you are getting addmission to prove your eligibilty.
best of luck!
According to cbse norms candidates who have completed class 10th, class 11th, have a gap year or have failed class 12th can appear for admission in 12th class.for admission in cbse board you need to clear your 11th class first and you must have studied from CBSE board or any other recognized and equivalent board/school.
You are not eligible for cbse board but you can still do 12th from nios which allow candidates to take admission in 12th class as a private student without completing 11th.
