If an object has a volume of 200 cubic feet and a unit weight of 150 pounds per cubic foot, what is its total weight?

If an object has a volume of 200 cubic feet and a unit weight of 150 pounds per cubic foot, what is its total weight?

• A. 350 pounds
• B. 450 pounds
• C. 30,000 pounds
• D. 300,000 pounds

Answer: (D)

To find the total weight of the object, you multiply its volume by its unit weight. In this case, the volume of the object is 200 cubic feet, and the unit weight is 150 pounds per cubic foot. Using the formula for weight: Total weight = Volume × Unit Weight Substituting the values: Total weight = 200 cubic feet × 150 pounds per cubic foot = 30,000 pounds. This calculation shows that the total weight is indeed 30,000 pounds. Understanding this calculation is critical in crane operations, as it helps in determining the capacity required for lifting and ensuring safe operations to avoid overloading the crane. The other options do not represent the correct calculation and therefore do not provide an accurate representation of the total weight of the object based on the given volume and unit weight.
