Answer:
x = (106 - 10) / 8
Explanation:
In total, the string is 106 inches long. The bow required 10 inches of string, so 94 inches of string were left over. The string crosses 8 faces of the cube in total, so you'd have to take 94 divided by 8 to get the largest amount of string each side would require. 94 divided by 8 is 11.75.
