Answer:
The volume of cube is increasing at a rate 7.5 cubic meter per hour.
Step-by-step explanation:
We are given the following in the question:
Surface area of cube = 24 square meters.
Let l be the edge of cube.
Surface area of cube =

Thus, at that instant the edge of cube is 2 meters.

We have to find the rate of change in volume.
Volume of cube =

Rate of change of volume =

Thus, the volume of cube is increasing at a rate 7.5 cubic meter per hour.
