What is total surface area mean?

The total surface area of a solid is the sum of the areas of all of the faces or surfaces that enclose the solid. The area of the rectangle is the lateral surface area. The sum of the areas of the rectangle and the two circles is the total surface area.

What is surface area in simple words?

Definition of surface area : the amount of area covered by the surface of something The lake has roughly the same surface area as 10 football fields.

How do you find surface area of a rectangle?

To find the area of the rectangle, just multiply the two edges together. Area (bottom edge) = length times width = lw. Going back to our example, the area of the bottom face is 4 inches x 3 inches = 12 square inches.

Is surface area a TSA or CSA?

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.

How do you find the total surface area of a cube?

Correct answer: The surface area of a cube = 6a2 where a is the length of the side of each edge of the cube. Put another way, since all sides of a cube are equal, a is just the lenght of one side of a cube.

What will be the total surface area of a right circular cylinder?

Surface Area of Right Circular Cylinder Formula ⇒ Total Surface Area (TSA) = 2πrh + 2πr2 = 2πr(h+r) square units.

What is the difference between surface area and total surface area?

Surface area means all the area that you can see in two dimensions – this means the length and width. The surface area of a wall is everything you can paint. 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.
