The volume of the cube is 64 find its sum of the lengths of all sides.

The sum of the lengths of all sides is the perimeter.

The perimeter of a cube is found by the formula: P = a * 12, where P is the perimeter of the cube, a is the length of the side of the cube.

We can calculate the length of a side of a cube since we know its area.

The formula for the area of a cube: S = a ^ 3, where S is the area of the cube, a is the length of the side of the cube.

Let’s find a.

64 = a ^ 3.

a = 4.

Now we can find the perimeter.

P = 4 * 12.

P = 48.

Answer: The perimeter of the cube is 48.
