Sodium chlorate crystals are easy to grow in the shape of cubes by allowing a solution of water and sodium chlorate to evaporate slowly. IfVis the volume of such a cube with side lengthx, calculate the derivative whenx= 5 mm.

V '(5) = ?

What does this quantity represent?

V '(5) represents the rate at which the volume is increasing with respect to the side length as V reaches 15 mm3.

V '(5) represents the rate at which the volume is increasing as x reaches 15 mm.

V '(5) represents the rate at which the volume is increasing with respect to the side length as x reaches 5 mm.

V '(5) represents the rate at which the side length is increasing with respect to the volume as x reaches 5 mm.

V '(5) represents the volume as the side length reaches 5 mm.

I dont' know wat to do? Do I need to do the derivatives? Please show me! Thank you!
