Dear Ishu
Thanks for asking us a question in Ask the Expert section of TopperLearning.com.
It depends upon the situation.
If the solid is an hollow cylinder or cone, we need to consider the curved surface area.
Or, else we may need to consider the total surface area.
Suppose if you to paint the water pipe, cylindrical in shape, we should consider the curved surface area.
Consider the example of painting a toy, cylindrical in shape, we should consider the total surface area.
In any case, you should practice more problems to get well versed with the appropriate formulae.
