Answer:
9 years
the tree doubles in height
we can make a model
1 x 2 = 2
2 x 2 = 4
4 x 2 = 8
8 x 2 = 16
16 x 2 = 32
32 x 2 = 64
64 x 2 = 128
128 x 2 = 256
256 x 2 = 512
512 x 2 = 1024
Let's say 1024 is the maximum height
half the maximum height is 1024 x 0.5 = 512 so it will take 9 years because it reached 512 on the 9th year

Step-by-step explanation:
The volume of the bigger rectangular tank is length × breadth ×height
V= l×b×h
V=80×60×40
V=192000
Volume of the smaller rectangular jar that will filled up the bigger one
V=l×b×h
V=20×10×15
V=3000
Then, the amount that will filled it up.
Bigger Volume / smaller volume
192000/3000=64
Therefore, 64 of the smaller volume will filled the bigger volume
