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

The volume of a rectangular prism is determined by multiplying its three dimensions: length, width, and height. This is because a rectangular prism can be thought of as a three-dimensional box, and the volume measures the amount of space inside that box.

To find the volume, you take the area of the base (which is the length multiplied by the width) and then multiply that area by the height of the prism. Thus, the correct formula for the volume is V = length * width * height.

This direct multiplication captures how many of those base areas fit into the height of the prism, providing an accurate measure of the entire space within the prism.
