How do you find the LSA of a cuboid?
The Total surface area of a cuboid (TSA) is equal to the sum of the areas of it’s 6 rectangular faces, which is given by:
- Total Surface Area of a Cuboid (TSA) = 2 (lw + wh + lh) square units.
- Lateral Surface Area of a cuboid (LSA) = 2 (lh + wh) = 2 h (l + w) square units.
- Example 1:
- Solution.
- Example 2:
- Solution:
How is the formula of cuboid derived?
Volume of a cuboid = l × b × h [cubic units] b = breadth. h = height.
What is the formula of lateral surface area?
This lateral surface area can be calculated by multiplying the perimeter of the base by the height of the prism. For a right circular cylinder of radius r and height h, the lateral area is the area of the side surface of the cylinder: A = 2πrh.
What is the formula of CSA of cylinder?
2πrh sq. units
Curved Surface Area (CSA) of Cylinder It is also called Lateral surface area (LSA). The CSA of a cylinder having its base radius ‘r’ and height ‘h’ is given by: Curved surface area (CSA) of cylinder = 2πrh sq. units.
Is CSA and LSA same?
Basically, the surface area can be classified as: 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.
How is the volume of a cube derived?
The formulas to find the volume of a cube are:
- V = s3, where s is the edge length of the cube.
- V = √3×d3/9, where d is the diagonal length of the cube.
What is LSA 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 does LSA mean in math?
LSA stands for Lateral surface area. while. CSA stands for Curved surface area ! LSA is used for figures which haves constant shape like cuboid , cube , etc while CSA is used to say for spheres , hemispheres ,etc !!
What is Cone CSA?
Curved Surface Area (CSA) = πrl. Here, r = Radius of the circular base of the cone. l = Slant height of the cone. When the cone is in the form of an unrolled lateral area, r is referred to as the length of the arc of a sector and l is referred to as the radius of the sector.
What is 2 pi rh?
The lateral surface of an object is defined as the area of a curved surface, excluding the area of its base and top. In the lateral surface area of a cylinder, the radius is directly proportional to the height of the Cylinder. The Curved Surface Area of the Cylinder = 2 \pi r h.
