Question

I need help like nowww please ok.

Marie can find the volume of a cube by using the formula V = s³, where s represents the side length of the cube. If Marie’s cube has a side length of 2 1\2
centimeters, what is the volume of her cube? Show your work. Make sure that you include the correct unit of measure in your answer.

Answer 1

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

Explanation:

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

Side length of Marie’s cube is
`2(1)/(2)\ cm=(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=((5)/(2))^3\ cm^3\\\\=(125)/(8)\ cm^3\\\\=15.625\ cm^3`

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