What is the volume of a cube with side length 2 cm?

Explanation:
Volume of a cube comes from multiplying its side length by itself three times. With a side length of 2 cm, the volume is 2 cm × 2 cm × 2 cm = 8 cm^3. This works because every edge is the same, so the space inside scales with the cube of the edge length. You can picture filling the cube with 1 cm × 1 cm × 1 cm unit cubes: along each dimension you fit 2, giving 2 × 2 × 2 = 8 small cubes, each of volume 1 cm^3, totaling 8 cm^3.
