A white board is a rectangular-shaped 3D object typically made of a smooth, rigid material such as porcelain, melamine, or glass. It has a glossy and slightly reflective surface that is usually white in color, enabling it to serve as a writable and erasable board. The edges of the white board are straight and sharp, enhancing its geometric appearance. It is mounted on a wall or supported by an easel, providing a flat and elevated surface for writing or drawing with dry erase markers. The white board's dimensions can vary, but it predominantly possesses a long width and a relatively shorter height, resembling a stretched-out window or a large, frameless painting. The thinness of the board gives it a lightweight and minimalist feel, while also making it easy to move and transport. The surface of the white board remains blank until information is added to it, making it both a functional tool for presenting ideas and a visually clean and sleek object. Overall, a white board represents a versatile and essential object commonly used in educational, professional, and creative settings to foster collaborative learning, brainstorming, and communication.
