Hello,

• The surface area of any given object is the area or region occupied by the surface of the object. It can be of two types - Curved Surface Area (CSA) and Total Surface Area (TSA)

• Volume is the amount of space available in an object.

• Both Surface Area and Volume are studies for 3-D objects.

-------- Given below I have mentioned Surface Areas and Volume of Few 3-Dimensional Objects -

• Cuboid -

- CSA - 2h(l + b)

- TSA - 2(lb + bh + hl)

- Volume - l * b * h

• Cube -

- CSA - 4a^2

- TSA - 6a^2

- Volume - a^3

• Cylinder

- CSA - 2πrh

- TSA - 2πr(r + h)

- Volume - πhr^2

• Sphere -

- CSA - 4πr^2

- TSA - 4πr^2

- Volume - 4/3π r^3

• Cone -

- CSA - πrl

- TSA - πr(r + l)

- Volume - 1/3πhr^2

• Hemisphere -

- CSA - 2πr^2

- TSA - 3πr^2

- Volume - 2/3π r^3

I hope you find the answer helpful.

Thank you

Hello there

See, from the terms of mathematics, area is the amount of space or you can also say the amount of surface which you've mentioned occupied by any two-dimensional flat object in a plane. Its unit is in square units.

Whereas, volume is defined by the space occupied by the three-dimensional object in a 3-D orientation. Its unit is in cubic units.

I hope it helps you!

Thank you!
