What Is Surface Area and Volume?

Surface Area and Volume are two different measurements. Surface area tells us how much space the outer surface of a solid covers. For example, the surface area of a box tells us the total area of all its faces. Volume tells us how much space a solid object takes up. For example, the volume of a water tank tells us how much water it can hold. Thus, Surface Area and Volume help us understand the size and space of solid objects. 

Important Formulas for Surface Area and Volume

Students preparing for JNVST Class 9 Maths Surface Area and Volume should learn the basic formulas. These formulas make questions easier and faster.


Cuboid

  • Total Surface Area = 2(lb + bh + hl)

  • Lateral Surface Area = 2h(l + b)

  • Volume = l × b × h

Here, l means length, b means breadth, and h means height.


Cube

  • Total Surface Area = 6a²

  • Lateral Surface Area = 4a²

  • Volume = a³

Here, a means the side of the cube.


Cylinder

  • Curved Surface Area = 2πrh

  • Total Surface Area = 2πr(r + h)

  • Volume = πr²h

Here, r means radius and h means height.


Cone

  • Curved Surface Area = πrl

  • Total Surface Area = πr(l + r)

  • Volume = 1/3 πr²h

Here, l means slant height.


Sphere

  • Surface Area = 4πr²

  • Volume = 4/3πr³


These formulas are useful for many Surface Area and Volume questions.
