Surface Area Formulas
Surface Area Formulas
Using the Surface Area Formulas, one can find the total area occupied by all the surfaces on any three-dimensional object.
What Is Surface Area Formula?
A three-dimensional object’s surface area can be found using the surface area formula. There are two types of Surface Area Formulas:
- Formula for curved surface area or formula for lateral surface area
- Formula for calculating total surface area
Surface Area Formulas of Different Shapes
A three-dimensional object has lateral surfaces and a base surface. Total surface area refers to the sum of lateral/curved surface area and base surface area.
Surface Area Formula of Cube
The surface area of a cube is the total area covered by its six faces.
- Surface area of the cube is equal to the sum of the area of its vertical surfaces and the area of its base. The surface area of a cube is calculated as 6a2 where a is the length of one side.
- The lateral surface area formula for a cube is the sum of its lateral side faces. In this case, LSA = 4a2, where a is the length of the side.
Surface Area Formula of Cuboid
The total surface area of the cuboid is calculated by adding the areas of all six faces. A cuboid’s total surface area and lateral surface area can be expressed in terms of its dimensions: length (l), breadth (b), and height (h).
