The question is basically asking you to calculate the new volume of the box that is 12x 7.5 x 2.5inches and to see if it has a larger volume than 162.5 sqin.
If you calculate the volume you should get 225 square inches.
Since there are 28 tens which is basically 28 rows of 10 all you have to do is 28 times 10. Whatever number times ten has a 0 after it so the answer is 280
