To find the side length of a cube with a volume of 27 cm³, we can follow the same steps as Tabitha:
Step 1: Write the equation using the formula for the volume of a cube, \( V = s^3 \). For a volume of 27 cm³, we have:
\[ 27 = s^3 \]
Step 2: Take the cube root of both sides:
\[ \sqrt[3]{27} = s \]
Step 3: Find the cube root of 27:
Since \( 3^3 = 27 \), we have:
\[ s = 3 \text{ cm} \]
So, the side length of the cube is \( 3 \text{ cm} \).
Therefore, the correct response is 3 cm.
