Overhead Crane Practice Test 2025 – 400 Free Practice Questions to Pass the Exam

To determine the weight of the object given its dimensions and weight per cubic foot, you start by calculating the volume of the object. The volume is found by multiplying the length, width, and height. For dimensions of 4 ft by 3 ft by 3 ft, the calculation is:

Volume = Length × Width × Height

Volume = 4 ft × 3 ft × 3 ft = 36 cubic feet

Next, to find the total weight of the object, you multiply the volume by the weight per cubic foot. The problem states that the weight per cubic foot is 150 lbs:

Total Weight = Volume × Weight per Cubic Foot

Total Weight = 36 cubic feet × 150 lbs/cubic foot = 5,400 lbs

However, this matches none of the provided options, which indicates that the weight was likely interpreted incorrectly. The choices provided don't lead to this total weight calculation, which suggests the question might focus singularly on the weight per cubic foot (which is given as 150 lbs).

Given the context of the question and the choices presented, the weight of a single cubic foot of the material is indeed 150 lbs. This weight per cubic foot is a constant value and critical in various applications
