Shanice bought eight hats. A week later half of all her hats were lots during a move. There were only 15 hats left. With how many hats did she start with?

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.

The answer is

If your are looking for the volume it would be 42997.5 in cubed
