## What is the difference between surface area and TSA?

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 total surface area?

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 sum of the areas of the rectangle and the two circles is the total surface area. This process can be imagined with each of the solids to picture the lateral surface and the base(s).

#### What is LSA and TSA?

LSA refers to lateral surface area. TSA refers to total surface area. LSA means the area of the lateral/curved surface. TSA means the area of the whole object.

**What is surface area examples?**

more 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.

**How do you write surface area?**

Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. 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.

## How do I know if I have TSA or CSA?

1. when it’s asked to find the area of a sheet required to make a cubical or cuboidal box, then u will use TSA. formula for cuboid is 2(lb+bh+lh) and for cube is 6a² and a is the length of the side. there is one more formula which is CSA+1 base.

### How do you find total area?

Multiply the length of the base, b, by the height, h, to find the total area. The equation for the area, A, of a square or rectangle area can be written as: A = b * h.

#### What is TSA of hemisphere?

The total surface area of the sphere = Curved surface area of sphere + base area. We know that the base of the hemisphere is circular in shape, use the area of the circle. TSA = 2πr2 + πr2 = 3πr2. Therefore, The total surface area of a hemisphere = 3πr2 square units.

**Is the total area the same as the surface area?**

The total surface area is made up of a circular top and bottom, which are each the same size, and the side surface, which is actually a rectangle. We must find the area of the top, or Areatop, which is the area of a circle with a radius of r.

**How to calculate surface area?**

Volume = (1/3) π r 2 h

## What is the total area of all surfaces of an object?

Surface Areas. The sum of the areas of all external surfaces of a three-dimensional object is called its total surface area (TSA).

### What is the formula for a surface area?

Circular Cylinder Surface Area Volume = π r 2 h Top Surface Area = π r 2 Bottom Surface Area = π r 2 Total Surface Area = L + T + B = 2 π rh + 2 ( π r 2) = 2 π r (h+r)
