A cube has all sides with a length of 7k^9n^8. The volume of a cube is found by raising the length of one side of the 3rd power. What is the final value of the coefficient when simplifying the expression?

Is the answer 343?

7*7*7=343

The volume of a cube is 343 cm find the length of an edge of a cube?

To find the volume of a cube, you need to raise the length of one side to the power of 3. In this case, the length of one side is 7k^9n^8.

To simplify the expression, you need to raise the coefficient (7) to the power of 3. This gives you 7^3 = 343.

So, the final value of the coefficient when simplifying the expression is indeed 343. Therefore, your answer of 343 is correct.
