# Total Surface Area of a Cuboid Calculator

A cuboid is a three-dimensional geometric solid shape with 6 faces. All corners of a cuboid are right angles and opposite faces or sides are equal. In other words, a cuboid is a solid figure bounded by six faces, forming a convex polyhedron. It can also be called as a rectangular cuboid. The total surface area (TSA) of a cuboid is the sum of the areas of its six faces. Use this online total surface area of a cuboid calculator to calculate the TSA of a rectangular cuboid.

#### Formula:

TSA = 2 x [(l x w) + (w x h )+ (l x h)]
**Where,**
TSA = Total Surface Area of a Cuboid
l = Length
w = Width
h = Height

#### Example

** If the length, width and height of the triangle are 5,7 and 10 m, then **

Total Surface Area = 2 x [(5 x 7) + (7 x 10 )+ (5 x 10)]

=310 m^{2}.
