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.
The length of the race is 5 kilometers.
5 kilometers equals 5000 meters.
Since Lana's avarege step length is about 0.5 meters, we need to divide 5000 by 0.5
Hence, Lana needs to take about 10000 steps.
