If the surface area of a cube is increasing at a rate of

3.6\,c{m^2}/\sec ,

retaining its shape; then the rate of change of its volume

(\mathrm{in}\,c{m^3}/\sec ),

when the length of a side of the cube is 10 cm is

View answer and explanation

Correct option: C

Option C (9) is correct because it is derived from finding the rate of change of the volume of the cube using the given rate of change of its surface area.
