There are nine 'different' slots we can fill in for each value. Thus, we get 9! different ways, including repetition.
Now, we need to account for repetition. This can be visualised as separate letters as below:
s₁ u c₁ c₂ e₁ s₂ s₃ e₂ s₄
We can arrange them like this, and we'd never know the difference:
s₁ u c₂ c₁ e₂ s₃ s₂ e₁ s₄
s₄ u c₁ c₂ e₁ s₁ s₃ e₂ s₂
Thus, we have overcounted by a factor of 2! (c's can change in 2! ways), 2! (e's can change in 2! ways), and 4! (s' can change in 4! ways).
Therefore, our final number of permutations becomes:

To find the volume of any cube you need to know the length, width and height. The formula to find the volume multiplies the length by the width by the height. The good news for a cube is that the measure of each of these dimensions is exactly the same. Therefore, you can multiply the length of any side three times.
Answer:
4+x=-3+2x
4+3=2x-x
7=x
9x=9*7
=63
