Hi there!
To find the volume of a cube, we must multiply its length, width and height. In a formula:
![volume = l * w * h](https://img.qammunity.org/2019/formulas/chemistry/high-school/77t3iugk78bmg6voxjt8xns4xyf9b8hvz9.png)
We can now plug in the data from the question into the formula. In this case it doesn't matter what exactly the width or length or height is [I mean their position in the formula], since we're multiplying.
![volume = 5.5 * 3 * 2 = 33](https://img.qammunity.org/2019/formulas/chemistry/high-school/gsudabcp2yjz7d0xd800ttob5k8ixygx6d.png)
Hence, the volume of the cube is 33 cm^3. In words: thirty-three cubic centimetres.
~ Hope this helps you!
