As stated by the equation, the volume of a rectangular prism (a juice box in this case) can be found by multiplying the length of the prism by its width, and then by the height. One way to think about this volume is that you are finding the area of a rectangle (length times width) and then multiplying that area by the height of the three dimensional shape.
