Given a cube with a volume of 64 in3. Find the length of the side (edge) of this cube.
The picture below shows the cube with the sides (edges) of length L.
Since the value of the volume is given, we substitute V with 64 in into the formula as shown:
Now, to find L, we just need to find the cube root of 64 as shown. Since 64 = 4×4×4, it is clear that cube root of 64 is 4. Also, since the unit for the volume is in3, the unit for L will be in.
Therefore, the answer is B.
