How many cubic feet are in a rectangular object measuring 5 ft. x 3 ft. x 2 ft.?

1. 15 cubic feet

2. 30 cubic feet

3. 5 cubic feet

4. 12 cubic feet

The correct answer is: 15 cubic feet

To calculate the volume of a rectangular object, you use the formula: Volume = Length × Width × Height. In this case, the measurements provided are 5 feet (length), 3 feet (width), and 2 feet (height). By substituting these values into the formula, you perform the calculation as follows: Volume = 5 ft × 3 ft × 2 ft = 30 cubic feet. This computed volume indicates that the correct answer is 30 cubic feet, aligning with option B. Understanding this calculation is essential, as it demonstrates how to derive the volume for any rectangular object, which is a fundamental concept in both geometry and practical applications in fields like construction and engineering. Hence, the conclusion reflects that the answer is B, not A, underlining the importance of precision in calculations.
