1. The formula for the volume of a cube is:
[
V = s^3
]
where ( s ) is the length of one side.
2. Since the volume ( V ) is given as 27 cubic feet, we can set up the equation:
[
s^3 = 27
]
3. To find ( s ), we take the cube root of both sides:
[
s = sqrt[3]{27} = 3 text{ feet}
]
4. Now, to find the area of one face of the cube, we use the formula for the area of a square:
[
text{Area} = s^2 = 3^2 = 9 text{ square feet}
]
So, the area of one of the faces of the cube is 9 square feet.
