A cuboid is a three-dimensional geometric shape with six rectangular faces. It is one of the most common 3D shapes encountered in daily life, resembling objects like boxes, bricks, and rooms. A cuboid is characterized by its length (\(l\)), width(\(w\)) and height (\(h\)) which form its dimensions.
The volume of a cuboid measures the space it occupies:
\[ V = lwh \]
where:
The surface area is the total area of all six faces of the cuboid:
\[ A = 2 (lw + wh + hl) \]
This formula sums the areas of each pair of opposite rectangular faces.
