Lateral Surface Area of cuboid is given by $2\left(l+b\right)h sq.units$

Concept: A cuboid is formed by three pairs of rectangles. Each pair of rectangles is opposite each other and equal in size.

A cuboid is a three-dimensional figure having six rectangular faces, twelve edges, and eight vertices that is used in geometry. A closed three-dimensional figure is encircled by rectangular faces, which are planar sections of rectangles, in the cuboid shape.

There are many real-life objects in the shape of a cuboid, such as brick, shoe-box etc…

Volume of cuboid is given by:

$\Rightarrow volume of cuboid = length \times width\times height= l\times b\times h$

And

Lateral surface area of cuboid $=2\left(l+b\right)h sq.units$.
