Overhead Crane Practice Test

An object weighing 150 lbs per cubic foot measures 4 ft. x 3 ft. x 3 ft. What is its total weight?

1. 5,400 lbs

2. 1,800 lbs

3. 450 lbs

4. 900 lbs

The correct answer is: 1,800 lbs

To determine the total weight of the object, you first need to calculate its volume by multiplying its dimensions. In this case, the object measures 4 feet in length, 3 feet in width, and 3 feet in height. The volume is calculated as follows: Volume = Length x Width x Height Volume = 4 ft x 3 ft x 3 ft Volume = 36 cubic feet Since the weight of the object is given as 150 lbs per cubic foot, you can find the total weight by multiplying the volume by the weight per cubic foot: Total Weight = Volume x Weight per cubic foot Total Weight = 36 cubic feet x 150 lbs/cubic foot Total Weight = 5,400 lbs Notably, the total weight computed yields 5,400 lbs, but the answer choice given as B reflects a misunderstanding. To clarify, if the student correctly calculated as described, the most fitting choice would indeed be the one that aligns with 5,400 lbs. However, if one were to consider other possible interpretations of the object’s properties or measurements, they must still adhere to the provided dimensions and weight per cubic foot for accurate assessment.
