The formula for the volume of a rectangular prism is V = l × w × h, where V is the volume, l is the length, w is the width, and h is the height of the prism.
To understand this better, think of a rectangular prism as a box. The length is how long the box is, the width is how wide the box is, and the height is how tall it is. When you multiply these three dimensions together, you’re essentially calculating how much space is inside the box, which gives you the volume. For example, if you have a box that is 2 units long, 3 units wide, and 4 units high, the volume would be 2 × 3 × 4 = 24 cubic units.
