Building with Bricks - Faces, Edges, and Corners

A brick is a solid three-dimensional (3D) shape known as a cuboid. Unlike a flat rectangle, it has depth and takes up space. Visual Description: Think of a standard rectangular box or a sponge; it has length, width, and thickness.

A face is the flat surface of a brick. A standard brick has exactly $6$ faces, and each face is a rectangle. Visual Description: If you hold a brick, you can see the top, bottom, front, back, and two side surfaces.

An edge is the straight line where two faces of the brick meet. A brick has $12$ edges. Visual Description: These are the long and short straight lines that form the skeleton or the frame of the brick.

A corner (also called a vertex) is the point where three edges of the brick meet. A brick has $8$ corners. Visual Description: These are the sharp, pointy tips at the very ends of the brick.

Brick patterns like 'Jaali' and 'Jharokha' are used to decorate walls. A 'Jaali' is a pattern of gaps (holes) in the wall that allows air and light to pass through, while a 'Jharokha' is a type of decorative window pattern. Visual Description: Jaali looks like a net or screen made of bricks, while Jharokha looks like a balcony frame built into the wall.

An Arch is a curved structure made of bricks often found over doors, windows, or bridges. Visual Description: It looks like a semi-circle or a 'U' shape turned upside down, supporting the weight of the wall above it.

Bricks are measured by three dimensions: Length ($l$), Breadth ($b$), and Height ($h$). When drawing a brick, we usually show three faces to give it a 3D look, even though it has six in total.
