The rate of change of area of a square

S

is equal to its side length. The rate of change of side of

S

is same as that of a cube

C

. The rate of change of volume of

C

when its side length is 2 units, is

View answer and explanation

Correct option: C

6

Option C (6) is correct because it is the rate of change of the volume of the cube when its side length is 2 units, calculated using related rates.
