A "slab" is a flat, thick piece of material, often made of stone, concrete, or wood. It is commonly used in construction and landscaping, serving as a foundation for buildings, walkways, or patios. For example, a concrete slab can provide a sturdy base for a house, ensuring stability and durability. In cooking, a slab can refer to a large piece of food, like a slab of meat or chocolate. Chefs might use a slab of beef to prepare a delicious steak or a slab of chocolate for desserts. In both contexts, slabs are versatile and essential for various practical applications.
