To find the length of each edge of a cube when you know the volume, you can use the formula for the volume of a cube, which is:
[
text{Volume} = (text{edge length})^3
]
Given that the volume is 64 cubic units, you set up the equation:
[
64 = (text{edge length})^3
]
To find the edge length, take the cube root of both sides:
[
text{edge length} = sqrt[3]{64} = 4 text{ units}
]
So, each edge of the cube is 4 units long.
