Answer:
The volume of her cube is [tex]15.625\ cm^3[/tex].
Step-by-step explanation:
The formula V = s³, where s represents the side length of the cube.
Side length of Marie’s cube is [tex]2\dfrac{1}{2}\ cm=\dfrac{5}{2}\ cm[/tex]
We need to find the volume of the cube. We can find the volume of the cube using the above formula as follows :
[tex]V=(\dfrac{5}{2})^3\ cm^3\\\\=\dfrac{125}{8}\ cm^3\\\\=15.625\ cm^3[/tex]
So, the volume of her cube is [tex]15.625\ cm^3[/tex].
