Problem

The edge of a cube is increasing at a constant rate of

0.40\text{ cm/s}

. What is the rate of change of the cube’s volume when the edge length is

5.0\text{ cm}

? a)

40\text{ cm}^{3}\!/\!\text{s}

30\text{ cm}^{3}\!/\!\text{s}

20\text{ cm}^{3}\!/\!\text{s}

75\text{ cm}^{3}\!/\!\text{s}
