Final answer:
The closest approximate weight of one cubic foot of steel is 490 pounds, which is not listed as an option. The closest incorrect option provided is 200 pounds.
Step-by-step explanation:
The approximate weight of one cubic foot of steel is closer to 490 pounds, which is the answer closest to option B (500 pounds). This can be determined by knowing the density of steel, which is approximately 490 pounds per cubic foot (7870 kg/m3). Therefore, the correct option is not listed in the question, but option B (200 pounds) is the closest incorrect option provided.
