What is the formula for calculating the volume of a rectangular prism?

• A. l × w
• B. l × w × h
• C. 2(l + w)
• D. l + w + h

Answer: (B)

The formula for calculating the volume of a rectangular prism is l × w × h, where l represents the length, w stands for the width, and h denotes the height. This formula works by calculating the area of the base of the prism (length multiplied by width) and then multiplying that area by the height to determine how much space is contained within the prism. This approach ensures that all three dimensions of the prism are accounted for, which is essential in accurately determining volume. Since volume measures the amount of three-dimensional space an object occupies, it is important to consider length, width, and height together. The other options either represent two-dimensional calculations (like just length times width for area) or linear measurements (like adding dimensions), which do not provide the complete volume calculation needed for a three-dimensional shape like a rectangular prism.
