Understanding Volume

This video tutorial introduces the concept of volume as a three-dimensional measurement of space within a closed shape. It explains how to calculate the volume of a cube using the formula V = s^3, where s is the side length, and verifies the calculation by dividing the cube into unit cubes. The tutorial also covers finding the volume of a rectangular box using the formula V = l × w × h, where l, w, and h are the length, width, and height, respectively. The video emphasizes the importance of using cubic units and provides examples to reinforce understanding.

What is the primary difference between area and volume in terms of measurement units?

• Area uses unit cubes, while volume uses unit squares.
