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:
- First, multiply the first two sides:
- 20cm × 20cm = 400cm²
- 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).
