Answer:
16 square feet
Step-by-step explanation:
First, let's find how long each side of the cube is.
The volume of a cube is found by this formula, where s is a side of the cube:
We can take the cube root of both sides:
Just flipping it:
We know our volume is 64 cubic feet. Let's put that into our equation as V:
The cubic root of 64 is 4, since 4 * 4 * 4 = 64
Thus, each side of our cube is 4 feet.
Now, the area of a side of our cube is found using this formula:
Since we know s, we can easily find the area A by squaring it:
