Hello!
We first have to find the volume of 3 cubes
The volume of a cube is [tex]a^{3} [/tex]
a is one side of the cube
We put 3 for A
We know that 3 cubes have a volume of 27
Now we find how many sets of 3 are in 156
156/3 = 52
Now we multiply the volume of 3 cubes by our result
27 * 52 = 1404
The answer is 1404 cubic feet
Hope this helps!
