Answer:
there is one solution in my opinion
Step-by-step explanation:
To calculate the cuboid's volume, use height×width×length which is 11×11×16
For the cylinder's volume, use πr²h. in this case, it is 3.14×4²×9
Add up the two answers you get and that's the solution

Taking natural logs of both sides, we get
0.015t=ln 3
t = ln 3/0.015 = 73.24
The answer is 73.24 years.
