# Quick Answer: What Is TSA And LSA?

## What is the LSA and TSA of cuboid?

TSA = 2(47) = 94 sq.cm.

Lateral surface area of a Cuboid: The sum of surface areas of all faces except the top and bottom face of solid is defined as the lateral surface area of a solid.

Consider a Cuboid of length, breadth and height to be l, b and h respectively..

## What is the difference between CSA and LSA?

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 TSA in math?

Consider a cylinder of radius r and height h. The total surface area (TSA) includes the area of the circular top and base, as well as the curved surface area (CSA).

## What is TSA of cylinder?

Total Surface Area of Cylinder The total surface area of a cylinder is equal to the sum of areas of all its faces. The Total surface area with radius ‘r’, and height ‘h’ is equal to the sum of the curved area and circular areas of the cylinder. TSA = 2π × r × h + 2πr2= 2πr (h + r) Square units.

## What is the formula of LSA of cube?

In the case of a cube, the lateral surface area consists of the area of four of the cube’s sides added together, or 4 times the area of one of the cube’s sides. Thus, the lateral surface area of a cube can be found using the formula 4s^2, where s is the side length of the cube.

## How do you find TSA and LSA?

if it is in the shape of cuboid then u will use 2h(l+b) and if it’s cube then it’s formula will be 4a² where a is the length of the side. 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.
