$74.088 {\text{ cm}}^{3}$
The volume of a cube with side length $s$ is ${s}^{3}$.
This is because the cube is a special case of a rectangular prism, whose volume is $l w h$. In the case of the cube, since all its sides are equal, the volme would be $s \cdot s \cdot s$, which equals ${s}^{3}$.
Since $s = 4.2$, the volume is ${4.2}^{3} = 74.088 {\text{ cm}}^{3}$.
