Answer:
216 cubes.
Step-by-step explanation:
The easiest way to take on this problem is to divide the side of the bigger cube by the smaller one.

Then, as in with volume, we cube this value to find the number of cubes necessary to fill such a space.

2 x (5-2)^3
2 x (3)^3
2 x 27
54
Answer:
No solution.
Step-by-step explanation:
(1/12)^-2b * 12^(-2b + 2) = 12
1/12 is basically the same thing as 12^-1.
12^(-1 * -2b) * 12^(-2b + 2) = 12
12^2b * 12^(-2b + 2) = 12
12^(2b - 2b + 2) = 12
12^2 = 12
Since the answers don't match up, the answer will be no solution.
Hope this helps!
