Answer:
875 cm cubed.
Explanation:
If the side length of a cube were 10 cm, the volume would be 10 * 10 * 10 = 1,000. So, the cube has a volume of 1,000 cm cubed.
A 5 cm square hole would have a volume of 5 * 5 * 5 = 125. So, the hole would have a volume of 125 cm cubed.
To find what's left, all you need to do is 1,000 - 125 = 875 cm cubed.
Hope this helps!
