Tabitha found the side length of a cube with a volume of 512 cm3

To find the side length of a cube with a volume of 27 cm³, we can follow the same steps Tabitha used.

1. Cube Volume Formula: The volume of a cube \( V \) is given by the formula \( V = s^3 \).
2. Substitute the value into the formula: We have \( 27 = s^3 \).
3. Take the cube root of both sides: \( \sqrt[3]{27} = s \).
4. Calculate the cube root: \( s = 3 \) cm, because \( 3^3 = 3 \times 3 \times 3 = 27 \).

The side length of the cube is 3 cm.

So, the correct response is 3 cm.
