Answer:

7 by 7 by 7

Step-by-step explanation:

The equation for the volume of a cube is length*width*height. Since it is a cube and all the sides are thee same length it can also be written like width*width*width or width^3=volume

If the volume is 343, then w^3 (width) = 343

Now we can type it in our calculator. the cube root of 343 is 7 wich means the cube has a side length of 7 inches.
