Final answer:
Floor-mounted equipment should generally be elevated at least 4 inches (10 centimeters) from the floor to ensure proper ventilation and prevent damage.
Step-by-step explanation:
In engineering, the height at which floor-mounted equipment should be from the floor depends on the specific equipment and its intended use.
However, in general, floor-mounted equipment should be elevated at least 4 inches (10 centimeters) from the floor. This height allows for proper ventilation, ease of maintenance, and to prevent damage from water or other potential hazards on the floor.
