This question is very confusing, because the answer is 100%. The box is not even over 70% and is no way of telling since none of the values are shown.
In your given expression, you group x and 6y since they are in parentheses, <span>The associative property tells you that you can change the grouping in an addition.
</span>Don't change the order of the things you're adding, but change just the grouping.<span>
</span><span>Group the 3 and the x together. Use parentheses.</span>
These are the possible dimensions:
1) 12 x 1 x 1
2) 6 x 2 x 1
3) 3 x 4 x 1
4) 3 x 2 x 2
92 points divide it by 2 and that’s your answer
