Answer 1

Answer:

The volume of her cube is $15.625\ cm^3$.

Step-by-step explanation:

The formula V = s³, where s represents the side length of the cube.

Side length of Marie’s cube is $2\dfrac{1}{2}\ cm=\dfrac{5}{2}\ cm$

We need to find the volume of the cube. We can find the volume of the cube using the above formula as follows :

$V=(\dfrac{5}{2})^3\ cm^3\\\\=\dfrac{125}{8}\ cm^3\\\\=15.625\ cm^3$

So, the volume of her cube is $15.625\ cm^3$.
