Question 368966: At what rate is the surface area of a cube increasing if its edges are 2 inches and are increasing at a rate of 3 inches per minute?
A=6s^2
dA/dt=12s (ds/dt)
dA/dt=12(2)(3)
dA/dt=72 in/min
Is this correct?

The value is correct but your units are not.
It should be (in)(in%2Fmin)=in%5E2%2Fmin
Remember surface area is measured in square units.
