25. a car is being compacted into a rectangular solid. the volume is decreasing at a rate of 2 m3 /sec. the length and width of the compactor are square, but the height is not the same length as the length and width. if the length and width walls move toward each other at a rate of 0.25 m/sec, find the rate at which the height is changing when the length and width are 2 m and the height is 1.5 m.
