Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. … We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.
still, What is surface area examples?
The total area of the surface of a three-dimensional object. Example: the surface area of a cube is the area of all 6 faces added together.
next, What is lateral surface area and total surface area?
The lateral surface area is the area of all sides excluding the area of the base. Total surface area of any solid is the sum of areas of all the faces of the solid.
then, What is the total surface area of cylinder?
The formula to calculate the total surface area of a cylinder is given as, the total surface area of cylinder = 2πr(h + r), while the curved surface area of cylinder formula is, curved/lateral surface area of cylinder = 2πrh, where ‘r’ is the radius of the base and ‘h’ is the height of the cylinder.

What is external surface area?
The external surface area is equal to the mesopore surface area. Bet surface area corresponds to sum of the micro- and mesopore surface area. Therefore, it becomes always smaller than BET surface area.
What unit is surface area?
What is surface area? Surface area is the total area of the faces of a three-dimensional shape. Surface area is measured in square units.
What is the difference between surface and total surface area?
The lateral surface of an object is the area of all the faces of the object, excluding the area of its base and top. For a cube, the lateral surface area would be the area of four sides. Total surface area is the area of all the faces including the bases.
What is difference between curved surface area and total surface area?
Curved Surface Area (CSA) – It includes the area of all the curved surfaces. Lateral Surface Area (LSA) – It includes the area of all the surface excluding the top and bottom areas. Total Surface Area (TSA) – It includes the area of all the surfaces of the object including the bases.
What is the difference between total surface area and volume?

How do you find the external surface area of a cylinder?
To find the surface area of a cylinder add the surface area of each end plus the surface area of the side. Each end is a circle so the surface area of each end is π * r2, where r is the radius of the end. There are two ends so their combinded surface area is 2 π * r2.
Is surface area a vector or scalar?
Complete answer:
Surface area is a scalar amount since it has magnitude just and no direction.So the right answer will be scalar which is the option A.
What is surface area used for?
The surface area of a three-dimensional object is the total area of all of its surfaces. Surface area is important to know situations where we want to wrap something, paint something, and eventually while building things to get the best possible design.
Where is total surface area and curved surface area used?
Surface Area Formula of Cone
If the radius of the base of the cone is “r” and the slant height of the cone is “l”, the surface area of a cone is given as: Total surface area of a cone, T = πr(r + l) The curved surface area of a cone, S = πrl.
Where do we use total surface area?
For a two-dimensional object, that’s also its total surface area. In three dimensions, like a cube, a sphere, or a pyramid, the surfaces can’t all be seen at one time. Total surface area in that case means adding up the areas of all the surfaces. For a cube, that means adding up the surface area of all six sides.
