Lateral/ Curved Surface Area:

The LSA/CSA of a figure refers to the surface area of a 3D figure excluding the area of the two bases. For 3D figures such as cube and cuboid, this area is referred to as LSA and for figures such as cylinder and cone that have a curved surface, this area is referred to as curved surface area. It is measured is cm square or meter square. A sphere's CSA is not taken into c

Total Surface Area:

The area of a figure include the bases is known as total surface area. This is the sum of the lateral surface area and the sum of the area of the two bases. It is also measured is cm or m square.

Volume:

The amount of material that can be stored in a particular object refers to the volume. This can also mean the amount of material used to make this figure. The volume of a figure is measured in cm or m cube.

Extra Bytes:

In order find the Total surface area of a prism:

Lateral surface area + 2 x Base Area

In order to find Volume of a prism:

Base area x height
