Answer:
The answer is 25.125
Explanation:
The answer would be 25.125 cubic inches because if you take the volume of a cube that has one side of 3.5 just multiply 3.5x3.5x3.5. This would give you 42.875. Then you have the area of a base which is already squared and you would multiply that with 4.25 to get 68 in cubed. You then know that 42.875 is the volume of the speaker and you are putting it in the box that has a volume of 68. To find what volume is left, you would subtract 42.875 from 68 to get 25.125 in cubed.
