To determine the weight of an object, you need to calculate its volume and then use the weight per cubic foot to find the total weight.
First, calculate the volume of the object using the dimensions provided: 4 feet long, 3 feet wide, and 3 feet high. The formula for volume is length multiplied by width multiplied by height:
Volume = Length x Width x Height Volume = 4 ft x 3 ft x 3 ft = 36 cubic feet.
Next, you have the weight per cubic foot, which is given as 150 lbs per cubic foot. To find the total weight of the object, you multiply 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 = 5,400 lbs.
Thus, the correct total weight of the object is 5,400 lbs. This demonstrates how to apply the concepts of volume and density to find the weight of an object in an overhead crane operation context.
