Detailed Solution

Concept: AIn order to answer this question, we must visualise a matchbox or hold a book in our hands and count the number of faces on each. Since all of these effects have cuboidal shapes, the number we will gain corresponds to the number of faces a cuboid possesses.
Before pacing with this question, let us see what a cuboid is. In figure, a cuboid is defined as a convex polyhedron bounded by six quadrilateral faces. We can also say that the faces of the cuboid can be any quadrilateral. Now, we can explain in simpler terms that cuboids are made of 6 blocks, which are placed at right angles. When we consider objects like a rustic box, a matchbox, a chalk box, a book,etc., we can see that they've a analogous shape. All these objects are made of six blockish aeroplanes.
and therefore we can say that the shape of these objects is a cuboid. We also have a shape cell. The introductory difference between a cell and cuboid is that a cell has equal length, height and breadth whereas a cuboid may or may not have the same
Volume of the cuboid = l × b × h = l × b × h [20]
Where l = length, b = breadth and h = height.
Let us consider the figure for a cuboid as below,
Face It's also called angles or sides. A cuboid has six faces which are all quadrilaterals. We can say that these quadrilaterals are actually blocks. We can see that each face has four equal sides and all four interior angles are right angles in a blockish cuboid.
Edge A line member formed where two edges meet. Looking at the figure, we can see that the cuboid has 12 edges.
Vertex A point formed where three edges meet. From the figure, we can see that there are 8 similar vertices.
Hence, the final answer is option 2.
