Final answer:
The formula to find the volume of a rectangular solid is V = l * w * h, representing the product of its length, width, and height.
Step-by-step explanation:
To find the volume of a rectangular solid, the correct formula is V = l * w * h, where V represents volume, l is the length, w is the width, and h is the height of the solid. This formula is dimensionally consistent and reflects that the volume is the product of the three perpendicular dimensions of the solid.
For example, if a rectangular solid has a length of 5 cm, a width of 3 cm, and a height of 2 cm, its volume would be calculated as:
V = 5 cm * 3 cm * 2 cm = 30 cm3
