Answer: The base area of the cube is 25 square units.
Step-by-step explanation: A cube has six square faces, all of which are identical. The base area of a cube refers to the area of one of these square faces.
The formula for the volume of a cube is:
V = s^3
where V is the volume of the cube and s is the length of one side of the cube.
If we know the volume of the cube is 125 cubic units, we can solve for the side length:
125 = s^3
Taking the cube root of both sides, we get:
s = 5
Therefore, each side of the cube has a length of 5 units. The area of one of the square faces of the cube is:
A = s^2
A = 5^2
A = 25 square units
So the base area of the cube is 25 square units.
