Arectangular hat box has a volume of 5,184 cubic inches. the box is 2 feet long by 18 inches wide. what is the hat box's height?

The volume of a rectangular box equals the multiplication of its length times its width times its height, so we have:
v = length*width*height
plug in the data we have:
5184 = 2*18*height
5184 = 36*height
solve for height:
height = 5184/36
height = 144
hence the height is 144 feet
