Total Surface Area of Cuboid


Let us look at the properties of a Cuboid 

A cuboid is a box-shaped object.

It has six flat sides and all angles are right angles.

And all of its faces are rectangles.

It is also a prism because it has the same cross-section along a length. In fact it is a rectangular prism.

Examples of cuboids
Cuboids are very common in our world,from boxes to buildings we see them everywhere. We can even fit them inside other cuboids!

The Surface Area of the cuboid is found using the Formula:

A = 2WL + 2LH + 2HW

or

A= 2( WL + LH + HW )

Example: Find the Surface Area of this cuboid:

A = 2* 4 * 5 + 2 *5*10 + 3 * 10 * 4

= 40 + 100 + 80

= 220 square units.
