Question

All edges of a cube are expanding at a rate of 5 centimeters per second.
(a) How fast is the volume changing when each edge is 1 centimeter(s)?

Answer 1

\[V=s^3\] I can get derivative and plug in but I don't get the correct answer?

Answer 2

\[\frac{dV}{dt}=2s^2\frac{ds}{dt}\] should be the derivative but I don't know why I'm getting it wrong

Answer 3

dV/dt = 3s^2 * ds/dt

Answer 4

= 3 * 5

Answer 5

cant believe I put down a 2 -_- thanks
