Both dices are identical.
The edge length of each cube is 3 cm
If both cubes are equal this means that their volumes are equal as well, so the combined volume of both dices is equal to twice the volume of one of them.
The volume of one cube is calculated as:
[tex]V=a^3[/tex]
Where "a" represents the length of the side
So the volume combined of both dices is:
[tex]\begin{gathered} 2V=2a^3 \\ 2V=2(3)^3 \\ 2V=2\cdot27 \\ 2V=54\operatorname{cm}^3 \end{gathered}[/tex]
