Step-by-step explanation:
A typical manufacturer's code (nomenclature) for a standard wall cabinet that is 36" wide, 18" high, and 24" deep is determined by the manufacturer. Different manufacturers may have their own specific codes to identify their products. These codes can vary depending on the company's internal system and may include a combination of numbers, letters, and symbols. For example, one manufacturer's code for a standard wall cabinet with the given dimensions might be WC-361824.
