Surface Area and Volumes Class 10

In our day-to-day life, we come across a number of solids made up of combinations of two or more of the basic solids. They can have varying size depending upon their requirement.

What are Areas-

Area is defined as two dimensional measurement, which includes basic plane size.

Area can be of two types-

(i) Total surface area

(ii) Curved surface area (lateral surface area)

Total Surface area includes the area of all the surfaces of the solid, whereas the curved surface area includes the area of the surfaces excluding the base and the top surface.

Volume-

The amount of space, measured in cubic units, that an object or substance occupies.

It is prime important for the students to be aware of the various formulas for Surface Area and Volume of different solid surfaces.

Let us solve a few examples-
