Solution

## The correct option is C 6 faces, 12 edges, and 8 verticesThe wall is made of bricks which are cuboidal in shape. We know the following details about a cuboid: ⇒ Cuboids have 6 flat faces. Each of them is rectangular in shape. ⇒ There are a total of 12 edges in a cuboid that connect all the vertices. ⇒ From the three-dimensional analysis, a cuboid has 8 vertices. Hence, we can conclude that one brick has 6 faces, 12 edges, and 8 vertices.
