Question

Hi guys how to prepare suface area and volume

Answer 1

learn all the formula first.then do examples of NCERT.read the question twice or thrice to understand it.first try to do yourself if you can't be able then see example. after that do all the exercise. don't leave any question and if you can't understand then try to ask your prblm and find your answer.

Answer 2

<> The formula for cuboid
- volume = l×b×h cubic units.
- total surface area = 2(lb+bh+hl) sq units.
- laternal surface area = 2(l+b)×h sq units.

<> for cube.
- volume = a^3 cubic units.
- total surface area = 6a^2 sq units
- laternal surface area = 4a^2 sq units.

<> for cylinder.
- volume = π R²h cubic units.
- Total surface area = 2πR(R+h) sq units
- curved surface area = 2πRh.

<> for cone.
- volume = 1/3 π R² h cubic units.
- curved surface area = πRL.
- total surface area = πRL+πR² sq units.
Thanks!
