Should be %50 because half of all numbers are even and half are odd (don’t quote me on that though)
From the equation, we have
![h=-20, k =21 , a^2=20^2, b^2=21^2](https://tex.z-dn.net/?f=%20h%3D-20%2C%20k%20%3D21%20%2C%20a%5E2%3D20%5E2%2C%20b%5E2%3D21%5E2%20)
To find the vertex and focus, we have to use the following formula
![Vertices =(h, k+-a) \\ Focii = (h,k+-c)](https://tex.z-dn.net/?f=%20Vertices%20%3D%28h%2C%20k%2B-a%29%20%5C%5C%20Focii%20%3D%20%28h%2Ck%2B-c%29%20)
And
![c = \sqrt{a^2 + b^2} = \sqrt{400+441} = 29](https://tex.z-dn.net/?f=%20c%20%3D%20%5Csqrt%7Ba%5E2%20%2B%20b%5E2%7D%20%3D%20%5Csqrt%7B400%2B441%7D%20%3D%2029%20)
So, we have
![Vertices=(-21,20+-20) \\ Focii=(-21, 20+-29)](https://tex.z-dn.net/?f=%20Vertices%3D%28-21%2C20%2B-20%29%20%5C%5C%20Focii%3D%28-21%2C%2020%2B-29%29%20)
![Vertices =(-21,0),(-21,40) \\ focii=(-21,-9),(-21,49)](https://tex.z-dn.net/?f=%20Vertices%20%3D%28-21%2C0%29%2C%28-21%2C40%29%20%5C%5C%20focii%3D%28-21%2C-9%29%2C%28-21%2C49%29%20)

Answer:
The volume of her cube is
.
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](https://tex.z-dn.net/?f=2%5Cdfrac%7B1%7D%7B2%7D%5C%20cm%3D%5Cdfrac%7B5%7D%7B2%7D%5C%20cm)
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](https://tex.z-dn.net/?f=V%3D%28%5Cdfrac%7B5%7D%7B2%7D%29%5E3%5C%20cm%5E3%5C%5C%5C%5C%3D%5Cdfrac%7B125%7D%7B8%7D%5C%20cm%5E3%5C%5C%5C%5C%3D15.625%5C%20cm%5E3)
So, the volume of her cube is
.
