Calculating the Volume of a Cube: A Step-by-Step Guide for Students

To find the volume of a cube, we can use the formula:

Volume = side × side × side

In this case, the side length of the cube is 20cm. So we can plug in the values:

Volume = 20cm × 20cm × 20cm

Now, let's do the multiplication step by step:

1. First, multiply the first two sides:
• 20cm × 20cm = 400cm²
2. Next, multiply the result by the third side:
• 400cm² × 20cm = 8000cm³

Therefore, the volume of a cube with dimensions 20cm x 20cm x 20cm is 8000 cubic centimeters (cm³).
