# Curved Surface Area (CSA) of Cuboid Calculator

A Cuboid is a 3D shape. It is a convex polyhedron bounded by six quadrilateral faces. The Curved surface area of a cuboid is the sum of the areas of its 6 faces. The surface area is the total area of all the faces of a 3D shape. Online Curved surface area of cuboid calculator helps you to calculate CSA Of Cuboid with the help of Height, Length and Breadth. First multiply the height with 2 and add the length and breadth. Finally, multiply these both values to get CSA.

#### Formula:

A = 2h(l+b)
**Where,**
A = Curved Surface Area of Cuboid
h = Height
l = Length
b = Breadth

#### Example

The length, height and breadth of a cuboid are 5mm, 7mm and 12mm. Find the curved surface area.

**CSA = 2h(l+b)**

= 2 x 7(5+12)

= 238 mm^2.
