The rate of change show more 89. The problem states that "the volume of a cube is increasing at the rate of 1200 cm cubed/min at the instant that the edges are 20 cm." (Look for the key word "rate" to spot a derivative.) The first part, "the volume is increasing at the rate of," gives dV/dt = 1200 cm^3/min, and the second part, "the edges are 20 cm," gives x = 20.
