What is the formula for the volume of a rectangular solid?

The volume of a rectangular solid is determined by the product of its length, width, and height. This relationship is captured by the formula V = lwh, where "V" represents volume, "l" is length, "w" is width, and "h" is height.

When you multiply these three dimensions together, you effectively measure the amount of space the solid occupies. This formula holds true for all rectangular solids, whether they are cubes or cuboids, as long as the measurements for length, width, and height are known.

In contrast, the other formulas mentioned do not accurately represent how to calculate the volume for this type of solid. They either incorporate addition instead of multiplication or involve extra modifications that may apply to different calculations, such as surface area or perimeter, rather than volume. Therefore, recognizing that volume requires a multiplicative relationship between all three dimensions is key to understanding why the formula V = lwh is correct.
