What is the formula used to find the volume of a rectangle?

The formula for calculating the volume of a rectangular prism, which is essentially a 3-dimensional box, is derived from understanding that volume represents the amount of space within an object. To determine this volume, you multiply the three dimensions of the rectangle: length, height, and width.

When you multiply these dimensions together (Length x Height x Width), you account for the total space contained within the object, making this method effective and universally applicable for any rectangular shape.

In contrast, the other options do not correctly represent the calculation for volume. For example, simply adding (length + height + width) does not provide a measure of space; rather, it combines dimensions in a way that is not relevant to volume. Subtraction or division also fails to capture the idea of volume since they do not reflect how the dimensions interact to fill the three-dimensional space.

Thus, using multiplication of length, height, and width accurately produces the volume of a rectangular shape.
