A manufacturer Phils various size boxes of flour. Today, the box and are 12 inches tall, 8 inches wide and 3 inches deep. They adjust the filling machine so it only feels the box until the product is 1.5 inch from the top of the box. How many cubic inches of flour a while they save by not filling the box to the top?
Here is what I got:(maybe wrong) 12*8*3 = 288, which is how big the box is. Then, you remove 1.5 inches from the height and get 10.5*8*3, which is 252. Subtract 252 from 288 to get the answer, 36.
