An edge of a variable cube is increasing at the rate of
\( \mathrm{P} \)
\( 3 \mathrm{~cm} / \mathrm{sec} \). How fast is the volume of the cube
W
increasing when the edge is \( 10 \mathrm{~cm} \) long?
(1) \( 900 \mathrm{~cm}^{3} / \mathrm{sec} \)
(2) \( 90 \mathrm{~cm}^{3} / \mathrm{sec} \)
(3) \( 300 \mathrm{~cm}^{3} / \mathrm{sec} \)
(4) \( 30 \mathrm{~cm}^{3} / \mathrm{sec} \)
