Mensuration — formula, example and practice

2D then 3D. Keep π = 22/7 or 3.14 consistent inside one question.

Content type: original worked example. Not labelled as a previous-year question.

Formula

Rectangle area = l×b · Circle area = πr² · Cuboid volume = l×b×h

Measure length, area and volume. 2D first, 3D second.

What you should learn here

Surface area questions often want CSA (side only) not TSA (including lids). Read “open pipe / closed box”.

Worked example

Question. Area of a circle with radius 7 cm (π = 22/7).

Solution. 22/7 × 49 = 154 cm².

Common mistake. Mixing diameter and radius, or using π = 22/7 in one step and 3.14 in the next.

When to use the shortcut. Write units in the answer. Board papers deduct for missing cm² vs cm³.

FAQs

Are these previous-year SSC questions?

No year or shift is claimed on these pages. Each maths section has 150 original practice MCQs. When a verified source database exists, a question will show exam + year; until then it is practice.

Where are Class 10 board formulas?

The CBSE formula sheet at /cbse/class-10/mathematics/formulas/ stays the canonical board list. This maths hub links to it instead of copying every line.

Do you publish tricks that are only sometimes true?

Every shortcut page states when the trick must not be used. A speed trick that fails on close options is not published as if it were a theorem.
