For this case we are asked the following question:
"What is the volume of the rubick's cube whose edge measures 3 cm"
By definition, the volume of a cube is given by:
![V = l ^ 3](https://img.qammunity.org/2020/formulas/mathematics/middle-school/lwqlfg4cy6ejbypb2rru0hx44ydhjnxrdk.png)
Where:
l: Is the side or the edge of the cube
According to the statement we have:
![l = 3 \ cm](https://img.qammunity.org/2020/formulas/mathematics/middle-school/qe7ue0mtsobb5rpqfqoesptreybsp976q0.png)
Substituting:
![V = 3 ^ 3\\V = 3 * 3 * 3\\V = 27](https://img.qammunity.org/2020/formulas/mathematics/middle-school/bqokwjojd3dzrcmpw4h4cm7lu82cvu8m1e.png)
Finally, the volume of the cube is
![27 \ cm ^ 3](https://img.qammunity.org/2020/formulas/mathematics/middle-school/twdq3ftiuuthp2qeola838dr6u8sc6wxyj.png)
Answer:
![27 \ cm ^ 3](https://img.qammunity.org/2020/formulas/mathematics/middle-school/twdq3ftiuuthp2qeola838dr6u8sc6wxyj.png)
