Formula: The volume is calculated by multiplying the area of the base by the height of the prism. We can express this with the formula: Volume (V) = length (l) × width (w) × height (h).

Imagine tiny cubes: Think of filling the prism with tiny cubes. The number of cubes required to fill the base represents the base area. By multiplying that number by the number of cube layers (height), you get the total volume.

Units: Remember to pay attention to the units of measurement you're using for length, width, and height (e.g., centimeters, inches). The final volume will be in cubic units (e.g., cubic centimeters, cubic inches).
For example, if a rectangular prism has a length of 5 cm, a width of 4 cm, and a height of 3 cm, its volume would be:
V = 5 cm × 4 cm × 3 cm = 60 cubic cm
