Answer:

4

Explanation:

To find the area of a cube, we have to multiply the width, height, and length, which, since they are all the same value, would be a side multiplied by itself 3 times(cubed). So, the area of this cube in terms of a(side) is a*a*a or a^3. The area is given to be 64, so we can write:

a^3 = 64

With the equation, we can realize 4*4*4 is 64, meaning a is 4.

Answer:

a = 4 feet

Explanation:

Since it's a cube, we know that each value will be equal. Because of this, you can cube root the cube's volume to find a.


\sqrt[3]{64}=4

Therefore, a = 4 feet.
