A cube has a volume of 512 cubic mm. If all sides of the cube ae divided by 4, what will the resulting volume be?

kotegsom [21]

Volume of a cube = s³

Therefore, s³ = 512, meaning that s = 8.

The question asks what the resulting volume would be if all sides of the cube were divided by 4.

The current side measures 8, and we know that 8/4 = 2.

Thus, the resulting volume = s³ = 2³ = 8 cubic mm.
