Final answer:
The file cabinet has four drawers with dimensions of 2.5 ft long. To find the total weight of the cabinet and drawers, we multiply the weight per foot by the length of each drawer and add it to the weight of the empty cabinet. The total weight is 205 lb.
Step-by-step explanation:
The subject of this question is Physics. The question asks about the size of a file cabinet, specifically the dimensions of the drawers and the weight of the cabinet and drawers combined.
The dimensions of each drawer are 2.5 ft long. The weight of the drawers is given as 30 lb/ft. The empty cabinet weighs 25 lb.
To find the total weight of the cabinet and drawers, we can multiply the weight per foot by the length of each drawer and add it to the weight of the empty cabinet. Since all the drawers are the same size, we can multiply the weight per foot by the total length of all the drawers. The total weight of the cabinet and drawers is then 25 lb + (30 lb/ft * 2.5 ft * 4 drawers) = 205 lb.
