Answer:
144 sq. ft.
Step-by-step explanation:
In order to find the area, we have to know the length of the sides.
Since the figure is a cube, the way that the volume was found was by multiplying one side length by itself two times.
s^3 = cube volume.
So, to find the length of one side, we have to find the cube root of the volume.
= 12
Now that we know the side length, we just need to multiply it by itself to find the area of the floor space.
12 * 12 = 144
