Many entrance exams (like JEE, NDA, and even aptitude tests) include questions based on surface area and volume. Learning it well now gives you a strong head start.
Knowing surface area and volume helps you understand the space around you — how big, how full, or how much something can hold. It’s not just about numbers, it’s about thinking smartly and using maths to solve practical problems. Surface Area and Volume is not just a chapter — it’s a life skill. Mastering it builds confidence, supports other subjects, and helps you succeed in exams and beyond. So, instead of memorising formulas blindly, take time to understand the “why” behind them — and you’ll never forget them.
Do you find it tricky to remember all the surface area and volume formulas? Or often mix up which one to use when solving problems? You’re not alone — but the good news is that with a few smart tips, this chapter can become one of the easiest to score full marks in.
Surface Area and Volume in Class 10 Maths is all about understanding shapes and how much space or area they take up. With regular practice and the right approach, you can master this topic in no time.
Understand, Don’t Just Memorise
Don’t just learn the formulas by heart — understand where they come from and what each part represents. For example, know the difference between curved surface area and total surface area, or volume and capacity.
Use Visuals and Diagrams
Always draw the solid shape mentioned in the question. A quick sketch helps you see what the question is asking and which formula fits best.
Keep a Formula Sheet Handy
Create a clean and simple sheet with all important formulas. Stick it near your study area so you can revise them quickly every day.
Be Careful with Units
Always check the units given in the question. Convert all measurements to the same unit before applying formulas. Remember:
Practice Mixed Questions
Try questions involving more than one shape (like a cylinder on top of a cone). These help you learn how to apply multiple formulas together and prepare you for tricky exam questions.
Revise Frustum Carefully
Frustum questions are often new for students. Understand how it's formed (by cutting a cone) and learn the specific formulas for its surface area and volume.
Solve Previous Year Papers
Practising past papers helps you spot common question types, improve speed, and reduce silly mistakes.
Highlight Important Words in Questions
Look out for words like curved, total, hollow, filled, or open from the top. These tell you exactly what the examiner is asking.
Try to relate problems to things around you — like water tanks, gift boxes, or footballs. When you connect maths to real life, it becomes easier to understand and remember.
With the right strategy, regular revision, and careful reading of the questions, Surface Area and Volume can become one of the highest-scoring chapters in your CBSE Class 10 Maths paper. Stay consistent, stay curious, and keep practising.

Do you often get the answer wrong even when you’ve used the right formula? Or lose marks over small calculation errors? You’re not alone. Many students make similar mistakes when solving surface area and volume questions — but the good news is, these can easily be avoided.
In Chapter 12: Surface Area and Volume, from the CBSE Class 10 Maths syllabus, success depends not just on knowing the formulas, but also on understanding how and when to use them correctly. Let’s take a look at the most common errors and how you can steer clear of them.
Many students mix up the concept of surface area (which is the outer covering of a shape) with volume (which is the space inside a shape). Always check what the question is asking — outer area or internal capacity?
Each shape — whether it's a cone, cylinder, or sphere — has its own specific formulas. Using the formula for a cylinder on a cone, or forgetting to add the base in total surface area, can lead to the wrong answer. Keep a formula sheet handy and double-check before solving.
One of the biggest mistakes is not converting all measurements to the same unit before applying the formula. For example, using centimetres and metres together will give you incorrect results. Always convert everything to a common unit first.
Some questions ask for curved surface area, some for total surface area, and others for volume. If you don’t read the question carefully, you might solve the wrong one. Highlight keywords like “open”, “closed”, “filled”, “painted”, or “capacity”.
Students often round π off incorrectly or use different values in the same question (like 3.14 in one step and 22/7 in another). Stick to one value throughout the problem, as mentioned in your textbook or question paper.
When working with cones, many students forget that the curved surface area formula uses the slant height (l), not the vertical height (h). If slant height isn’t given, calculate it using the Pythagoras theorem:
l = √(r² + h²)
Rushing through calculations or skipping steps can lead to small mistakes that cost big marks. Work neatly, write each step, and check your answer carefully.
In questions involving two or more shapes combined (like a cone on a cylinder), some students calculate for only one part. Make sure to add the surface areas or volumes of all parts as required.
