To find the length of one side of a cube given its volume, you can use the formula for the volume of a cube:
\[ V = s^3 \]
where \( V \) is the volume and \( s \) is the length of one side of the cube. Given that the volume \( V \) is 8 in³, you can set up the equation:
\[ s^3 = 8 \]
To find \( s \), take the cube root of both sides:
\[ s = \sqrt[3]{8} \]
Calculating the cube root of 8:
\[ s = 2 \text{ in.} \]
Thus, the length of one side of the cube is 2 in.
